It is backward-compatible with the current + OpenGL Utilities tesselator, and is intended to replace it. Here is + a summary of the major differences: + + - input contours can be intersecting, self-intersecting, or degenerate. + + - supports a choice of several winding rules for determining which parts + of the polygon are on the "interior". This makes it possible to do + CSG operations on polygons. + + - boundary extraction: instead of tesselating the polygon, returns a + set of closed contours which separate the interior from the exterior. + + - returns the output as a small number of triangle fans and strips, + rather than a list of independent triangles (when possible). + + - output is available as an explicit mesh (a quad-edge structure), + in addition to the normal callback interface. + + - the algorithm used is extremely robust. + + +The interface +------------- + + The tesselator state is maintained in a "tesselator object". + These are allocated and destroyed using + + GLUtesselator *gluNewTess( void ); + void gluDeleteTess( GLUtesselator *tess ); + + Several tesselator objects may be used simultaneously. + + Inputs + ------ + + The input contours are specified with the following routines: + + void gluTessBeginPolygon( GLUtesselator *tess ); + void gluTessBeginContour( GLUtesselator *tess ); + void gluTessVertex( GLUtesselator *tess, GLUcoord coords[3], void *data ); + void gluTessEndContour( GLUtesselator *tess ); + void gluTessEndPolygon( GLUtesselator *tess ); + + Within each BeginPolygon/EndPolygon pair, there can be zero or more + calls to BeginContour/EndContour. Within each contour, there are zero + or more calls to gluTessVertex(). The vertices specify a closed + contour (the last vertex of each contour is automatically linked to + the first). + + "coords" give the coordinates of the vertex in 3-space. For useful + results, all vertices should lie in some plane, since the vertices + are projected onto a plane before tesselation. "data" is a pointer + to a user-defined vertex structure, which typically contains other + information such as color, texture coordinates, normal, etc. It is + used to refer to the vertex during rendering. + + The library can be compiled in single- or double-precision; the type + GLUcoord represents either "float" or "double" accordingly. The GLU + version will be available in double-precision only. Compile with + GLU_TESS_API_FLOAT defined to get the single-precision version. + + When EndPolygon is called, the tesselation algorithm determines + which regions are interior to the given contours, according to one + of several "winding rules" described below. The interior regions + are then tesselated, and the output is provided as callbacks. + + + Rendering Callbacks + ------------------- + + Callbacks are specified by the client using + + void gluTessCallback( GLUtesselator *tess, GLenum which, void (*fn)()); + + If "fn" is NULL, any previously defined callback is discarded. + + The callbacks used to provide output are: /* which == */ + + void begin( GLenum type ); /* GLU_TESS_BEGIN */ + void edgeFlag( GLboolean flag ); /* GLU_TESS_EDGE_FLAG */ + void vertex( void *data ); /* GLU_TESS_VERTEX */ + void end( void ); /* GLU_TESS_END */ + + Any of the callbacks may be left undefined; if so, the corresponding + information will not be supplied during rendering. + + The "begin" callback indicates the start of a primitive; type is one + of GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, or GL_TRIANGLES (but see the + notes on "boundary extraction" below). + + It is followed by any number of "vertex" callbacks, which supply the + vertices in the same order as expected by the corresponding glBegin() + call. After the last vertex of a given primitive, there is a callback + to "end". + + If the "edgeFlag" callback is provided, no triangle fans or strips + will be used. When edgeFlag is called, if "flag" is GL_TRUE then each + vertex which follows begins an edge which lies on the polygon boundary + (ie. an edge which separates an interior region from an exterior one). + If "flag" is GL_FALSE, each vertex which follows begins an edge which lies + in the polygon interior. "edgeFlag" will be called before the first + call to "vertex". + + Other Callbacks + --------------- + + void mesh( GLUmesh *mesh ); /* GLU_TESS_MESH */ + + - Returns an explicit mesh, represented using the quad-edge structure + (Guibas/Stolfi '85). Other implementations of this interface might + use a different mesh structure, so this is available only only as an + SGI extension. When the mesh is no longer needed, it should be freed + using + + void gluDeleteMesh( GLUmesh *mesh ); + + There is a brief description of this data structure in the include + file "mesh.h". For the full details, see L. Guibas and J. Stolfi, + Primitives for the manipulation of general subdivisions and the + computation of Voronoi diagrams, ACM Transactions on Graphics, + 4(2):74-123, April 1985. For an introduction, see the course notes + for CS348a, "Mathematical Foundations of Computer Graphics", + available at the Stanford bookstore (and taught during the fall + quarter). + + void error( GLenum errno ); /* GLU_TESS_ERROR */ + + - errno is one of GLU_TESS_MISSING_BEGIN_POLYGON, + GLU_TESS_MISSING_END_POLYGON, + GLU_TESS_MISSING_BEGIN_CONTOUR, + GLU_TESS_MISSING_END_CONTOUR, + GLU_TESS_COORD_TOO_LARGE, + GLU_TESS_NEED_COMBINE_CALLBACK + + The first four are obvious. The interface recovers from these + errors by inserting the missing call(s). + + GLU_TESS_COORD_TOO_LARGE says that some vertex coordinate exceeded + the predefined constant GLU_TESS_MAX_COORD in absolute value, and + that the value has been clamped. (Coordinate values must be small + enough so that two can be multiplied together without overflow.) + + GLU_TESS_NEED_COMBINE_CALLBACK says that the algorithm detected an + intersection between two edges in the input data, and the "combine" + callback (below) was not provided. No output will be generated. + + + void combine( GLUcoord coords[3], void *data[4], /* GLU_TESS_COMBINE */ + GLUcoord weight[4], void **outData ); + + - When the algorithm detects an intersection, or wishes to merge + features, it needs to create a new vertex. The vertex is defined + as a linear combination of up to 4 existing vertices, referenced + by data[0..3]. The coefficients of the linear combination are + given by weight[0..3]; these weights always sum to 1.0. All vertex + pointers are valid even when some of the weights are zero. + "coords" gives the location of the new vertex. + + The user must allocate another vertex, interpolate parameters + using "data" and "weights", and return the new vertex pointer in + "outData". This handle is supplied during rendering callbacks. + For example, if the polygon lies in an arbitrary plane in 3-space, + and we associate a color with each vertex, the combine callback might + look like this: + + void myCombine( GLUcoord coords[3], VERTEX *d[4], + GLUcoord w[4], VERTEX **dataOut ) + { + VERTEX *new = new_vertex(); + + new->x = coords[0]; + new->y = coords[1]; + new->z = coords[2]; + new->r = w[0]*d[0]->r + w[1]*d[1]->r + w[2]*d[2]->r + w[3]*d[3]->r; + new->g = w[0]*d[0]->g + w[1]*d[1]->g + w[2]*d[2]->g + w[3]*d[3]->g; + new->b = w[0]*d[0]->b + w[1]*d[1]->b + w[2]*d[2]->b + w[3]*d[3]->b; + new->a = w[0]*d[0]->a + w[1]*d[1]->a + w[2]*d[2]->a + w[3]*d[3]->a; + *dataOut = new; + } + + If the algorithm detects an intersection, then the "combine" callback + must be defined, and must write a non-NULL pointer into "dataOut". + Otherwise the GLU_TESS_NEED_COMBINE_CALLBACK error occurs, and no + output is generated. This is the only error that can occur during + tesselation and rendering. + + + Control over Tesselation + ------------------------ + + void gluTessProperty( GLUtesselator *tess, GLenum which, GLUcoord value ); + + Properties defined: + + - GLU_TESS_WINDING_RULE.

When there are several + contours, the individual winding numbers are summed. This + procedure associates a signed integer value with each point x in + the plane. Note that the winding number is the same for all + points in a single region. + + The winding rule classifies a region as "inside" if its winding + number belongs to the chosen category (odd, nonzero, positive, + negative, or absolute value of at least two). The current GLU + tesselator implements the "odd" rule. The "nonzero" rule is another + common way to define the interior. The other three rules are + useful for polygon CSG operations (see below). + + - GLU_TESS_BOUNDARY_ONLY. Values: TRUE (non-zero) or FALSE (zero). + + If TRUE, returns a set of closed contours which separate the + polygon interior and exterior (rather than a tesselation). + Exterior contours are oriented CCW with respect to the normal, + interior contours are oriented CW. The GLU_TESS_BEGIN callback + uses the type GL_LINE_LOOP for each contour. + + - GLU_TESS_TOLERANCE. Value: a real number between 0.0 and 1.0. + + This specifies a tolerance for merging features to reduce the size + of the output. For example, two vertices which are very close to + each other might be replaced by a single vertex. The tolerance + is multiplied by the largest coordinate magnitude of any input vertex; + this specifies the maximum distance that any feature can move as the + result of a single merge operation. If a single feature takes part + in several merge operations, the total distance moved could be larger. + + Feature merging is completely optional; the tolerance is only a hint. + The implementation is free to merge in some cases and not in others, + or to never merge features at all. The default tolerance is zero. + + The current implementation merges vertices only if they are exactly + coincident, regardless of the current tolerance. A vertex is + spliced into an edge only if the implementation is unable to + distinguish which side of the edge the vertex lies on. + Two edges are merged only when both endpoints are identical. + + + void gluTessNormal( GLUtesselator *tess, + GLUcoord x, GLUcoord y, GLUcoord z ) + + - Lets the user supply the polygon normal, if known. All input data + is projected into a plane perpendicular to the normal before + tesselation. All output triangles are oriented CCW with + respect to the normal (CW orientation can be obtained by + reversing the sign of the supplied normal). For example, if + you know that all polygons lie in the x-y plane, call + "gluTessNormal(tess, 0.0, 0.0, 1.0)" before rendering any polygons. + + - If the supplied normal is (0,0,0) (the default value), the + normal is determined as follows. The direction of the normal, + up to its sign, is found by fitting a plane to the vertices, + without regard to how the vertices are connected. It is + expected that the input data lies approximately in plane; + otherwise projection perpendicular to the computed normal may + substantially change the geometry. The sign of the normal is + chosen so that the sum of the signed areas of all input contours + is non-negative (where a CCW contour has positive area). + + - The supplied normal persists until it is changed by another + call to gluTessNormal. + + + Backward compatibility with the GLU tesselator + ---------------------------------------------- + + The preferred interface is the one described above. The following + routines are obsolete, and are provided only for backward compatibility: + + typedef GLUtesselator GLUtriangulatorObj; /* obsolete name */ + + void gluBeginPolygon( GLUtesselator *tess ); + void gluNextContour( GLUtesselator *tess, GLenum type ); + void gluEndPolygon( GLUtesselator *tess ); + + "type" is one of GLU_EXTERIOR, GLU_INTERIOR, GLU_CCW, GLU_CW, or + GLU_UNKNOWN. It is ignored by the current GLU tesselator. + + GLU_BEGIN, GLU_VERTEX, GLU_END, GLU_ERROR, and GLU_EDGE_FLAG are defined + as synonyms for GLU_TESS_BEGIN, GLU_TESS_VERTEX, GLU_TESS_END, + GLU_TESS_ERROR, and GLU_TESS_EDGE_FLAG. + + +Polygon CSG operations +---------------------- + + The features of the tesselator make it easy to find the union, difference, + or intersection of several polygons. + + First, assume that each polygon is defined so that the winding number + is 0 for each exterior region, and 1 for each interior region. Under + this model, CCW contours define the outer boundary of the polygon, and + CW contours define holes. Contours may be nested, but a nested + contour must be oriented oppositely from the contour that contains it. + + If the original polygons do not satisfy this description, they can be + converted to this form by first running the tesselator with the + GLU_TESS_BOUNDARY_ONLY property turned on. This returns a list of + contours satisfying the restriction above. By allocating two + tesselator objects, the callbacks from one tesselator can be fed + directly to the input of another. + + Given two or more polygons of the form above, CSG operations can be + implemented as follows: + + Union + Draw all the input contours as a single polygon. The winding number + of each resulting region is the number of original polygons + which cover it. The union can be extracted using the + GLU_TESS_WINDING_NONZERO or GLU_TESS_WINDING_POSITIVE winding rules. + Note that with the nonzero rule, we would get the same result if + all contour orientations were reversed. + + Intersection (two polygons at a time only) + Draw a single polygon using the contours from both input polygons. + Extract the result using GLU_TESS_WINDING_ABS_GEQ_TWO. (Since this + winding rule looks at the absolute value, reversing all contour + orientations does not change the result.) + + Difference + + Suppose we want to compute A \ (B union C union D). Draw a single + polygon consisting of the unmodified contours from A, followed by + the contours of B,C,D with the vertex order reversed (this changes + the winding number of the interior regions to -1). To extract the + result, use the GLU_TESS_WINDING_POSITIVE rule. + + If B,C,D are the result of a GLU_TESS_BOUNDARY_ONLY call, an + alternative to reversing the vertex order is to reverse the sign of + the supplied normal. For example in the x-y plane, call + gluTessNormal( tess, 0.0, 0.0, -1.0 ). + + +Performance +----------- + + The tesselator is not intended for immediate-mode rendering; when + possible the output should be cached in a user structure or display + list. General polygon tesselation is an inherently difficult problem, + especially given the goal of extreme robustness. + + The implementation makes an effort to output a small number of fans + and strips; this should improve the rendering performance when the + output is used in a display list. + + Single-contour input polygons are first tested to see whether they can + be rendered as a triangle fan with respect to the first vertex (to + avoid running the full decomposition algorithm on convex polygons). + Non-convex polygons may be rendered by this "fast path" as well, if + the algorithm gets lucky in its choice of a starting vertex. + + For best performance follow these guidelines: + + - supply the polygon normal, if available, using gluTessNormal(). + This represents about 10% of the computation time. For example, + if all polygons lie in the x-y plane, use gluTessNormal(tess,0,0,1). + + - render many polygons using the same tesselator object, rather than + allocating a new tesselator for each one. (In a multi-threaded, + multi-processor environment you may get better performance using + several tesselators.) + + +Comparison with the GLU tesselator +---------------------------------- + + On polygons which make it through the "fast path", the tesselator is + 3 to 5 times faster than the GLU tesselator. + + On polygons which don't make it through the fast path (but which don't + have self-intersections or degeneracies), it is about 2 times slower. + + On polygons with self-intersections or degeneraces, there is nothing + to compare against. + + The new tesselator generates many more fans and strips, reducing the + number of vertices that need to be sent to the hardware. + + Key to the statistics: + + vert number of input vertices on all contours + cntr number of input contours + tri number of triangles in all output primitives + strip number of triangle strips + fan number of triangle fans + ind number of independent triangles + ms number of milliseconds for tesselation + (on a 150MHz R4400 Indy) + + Convex polygon examples: + +New: 3 vert, 1 cntr, 1 tri, 0 strip, 0 fan, 1 ind, 0.0459 ms +Old: 3 vert, 1 cntr, 1 tri, 0 strip, 0 fan, 1 ind, 0.149 ms +New: 4 vert, 1 cntr, 2 tri, 0 strip, 1 fan, 0 ind, 0.0459 ms +Old: 4 vert, 1 cntr, 2 tri, 0 strip, 0 fan, 2 ind, 0.161 ms +New: 36 vert, 1 cntr, 34 tri, 0 strip, 1 fan, 0 ind, 0.153 ms +Old: 36 vert, 1 cntr, 34 tri, 0 strip, 0 fan, 34 ind, 0.621 ms + + Concave single-contour polygons: + +New: 5 vert, 1 cntr, 3 tri, 0 strip, 1 fan, 0 ind, 0.052 ms +Old: 5 vert, 1 cntr, 3 tri, 0 strip, 0 fan, 3 ind, 0.252 ms +New: 19 vert, 1 cntr, 17 tri, 2 strip, 2 fan, 1 ind, 0.911 ms +Old: 19 vert, 1 cntr, 17 tri, 0 strip, 0 fan, 17 ind, 0.529 ms +New: 151 vert, 1 cntr, 149 tri, 13 strip, 18 fan, 3 ind, 6.82 ms +Old: 151 vert, 1 cntr, 149 tri, 0 strip, 3 fan, 143 ind, 2.7 ms +New: 574 vert, 1 cntr, 572 tri, 59 strip, 54 fan, 11 ind, 26.6 ms +Old: 574 vert, 1 cntr, 572 tri, 0 strip, 31 fan, 499 ind, 12.4 ms + + Multiple contours, but no intersections: + +New: 7 vert, 2 cntr, 7 tri, 1 strip, 0 fan, 0 ind, 0.527 ms +Old: 7 vert, 2 cntr, 7 tri, 0 strip, 0 fan, 7 ind, 0.274 ms +New: 81 vert, 6 cntr, 89 tri, 9 strip, 7 fan, 6 ind, 3.88 ms +Old: 81 vert, 6 cntr, 89 tri, 0 strip, 13 fan, 61 ind, 2.2 ms +New: 391 vert, 19 cntr, 413 tri, 37 strip, 32 fan, 26 ind, 20.2 ms +Old: 391 vert, 19 cntr, 413 tri, 0 strip, 25 fan, 363 ind, 8.68 ms + + Self-intersecting and degenerate examples: + +Bowtie: 4 vert, 1 cntr, 2 tri, 0 strip, 0 fan, 2 ind, 0.483 ms +Star: 5 vert, 1 cntr, 5 tri, 0 strip, 0 fan, 5 ind, 0.91 ms +Random: 24 vert, 7 cntr, 46 tri, 2 strip, 12 fan, 7 ind, 5.32 ms +Font: 333 vert, 2 cntr, 331 tri, 32 strip, 16 fan, 3 ind, 14.1 ms +: 167 vert, 35 cntr, 254 tri, 8 strip, 56 fan, 52 ind, 46.3 ms +: 78 vert, 1 cntr, 2675 tri, 148 strip, 207 fan, 180 ind, 243 ms +: 12480 vert, 2 cntr, 12478 tri, 736 strip,1275 fan, 5 ind, 1010 ms diff --git a/mesalib/src/glu/sgi/libtess/alg-outline b/mesalib/src/glu/sgi/libtess/alg-outline new file mode 100644 index 000000000..33fd69728 --- /dev/null +++ b/mesalib/src/glu/sgi/libtess/alg-outline @@ -0,0 +1,228 @@ +/* +*/ + +This is only a very brief overview. There is quite a bit of +additional documentation in the source code itself. + + +Goals of robust tesselation +--------------------------- + +The tesselation algorithm is fundamentally a 2D algorithm. We +initially project all data into a plane; our goal is to robustly +tesselate the projected data. The same topological tesselation is +then applied to the input data. + +Topologically, the output should always be a tesselation. If the +input is even slightly non-planar, then some triangles will +necessarily be back-facing when viewed from some angles, but the goal +is to minimize this effect. + +The algorithm needs some capability of cleaning up the input data as +well as the numerical errors in its own calculations. One way to do +this is to specify a tolerance as defined above, and clean up the +input and output during the line sweep process. At the very least, +the algorithm must handle coincident vertices, vertices incident to an +edge, and coincident edges. + + +Phases of the algorithm +----------------------- + +1. Find the polygon normal N. +2. Project the vertex data onto a plane. It does not need to be + perpendicular to the normal, eg. we can project onto the plane + perpendicular to the coordinate axis whose dot product with N + is largest. +3. Using a line-sweep algorithm, partition the plane into x-monotone + regions. Any vertical line intersects an x-monotone region in + at most one interval. +4. Triangulate the x-monotone regions. +5. Group the triangles into strips and fans. + + +Finding the normal vector +------------------------- + +A common way to find a polygon normal is to compute the signed area +when the polygon is projected along the three coordinate axes. We +can't do this, since contours can have zero area without being +degenerate (eg. a bowtie). + +We fit a plane to the vertex data, ignoring how they are connected +into contours. Ideally this would be a least-squares fit; however for +our purpose the accuracy of the normal is not important. Instead we +find three vertices which are widely separated, and compute the normal +to the triangle they form. The vertices are chosen so that the +triangle has an area at least 1/sqrt(3) times the largest area of any +triangle formed using the input vertices. + +The contours do affect the orientation of the normal; after computing +the normal, we check that the sum of the signed contour areas is +non-negative, and reverse the normal if necessary. + + +Projecting the vertices +----------------------- + +We project the vertices onto a plane perpendicular to one of the three +coordinate axes. This helps numerical accuracy by removing a +transformation step between the original input data and the data +processed by the algorithm. The projection also compresses the input +data; the 2D distance between vertices after projection may be smaller +than the original 2D distance. However by choosing the coordinate +axis whose dot product with the normal is greatest, the compression +factor is at most 1/sqrt(3). + +Even though the *accuracy* of the normal is not that important (since +we are projecting perpendicular to a coordinate axis anyway), the +*robustness* of the computation is important. For example, if there +are many vertices which lie almost along a line, and one vertex V +which is well-separated from the line, then our normal computation +should involve V otherwise the results will be garbage. + +The advantage of projecting perpendicular to the polygon normal is +that computed intersection points will be as close as possible to +their ideal locations. To get this behavior, define TRUE_PROJECT. + + +The Line Sweep +-------------- + +There are three data structures: the mesh, the event queue, and the +edge dictionary. + +The mesh is a "quad-edge" data structure which records the topology of +the current decomposition; for details see the include file "mesh.h". + +The event queue simply holds all vertices (both original and computed +ones), organized so that we can quickly extract the vertex with the +minimum x-coord (and among those, the one with the minimum y-coord). + +The edge dictionary describes the current intersection of the sweep +line with the regions of the polygon. This is just an ordering of the +edges which intersect the sweep line, sorted by their current order of +intersection. For each pair of edges, we store some information about +the monotone region between them -- these are call "active regions" +(since they are crossed by the current sweep line). + +The basic algorithm is to sweep from left to right, processing each +vertex. The processed portion of the mesh (left of the sweep line) is +a planar decomposition. As we cross each vertex, we update the mesh +and the edge dictionary, then we check any newly adjacent pairs of +edges to see if they intersect. + +A vertex can have any number of edges. Vertices with many edges can +be created as vertices are merged and intersection points are +computed. For unprocessed vertices (right of the sweep line), these +edges are in no particular order around the vertex; for processed +vertices, the topological ordering should match the geometric ordering. + +The vertex processing happens in two phases: first we process are the +left-going edges (all these edges are currently in the edge +dictionary). This involves: + + - deleting the left-going edges from the dictionary; + - relinking the mesh if necessary, so that the order of these edges around + the event vertex matches the order in the dictionary; + - marking any terminated regions (regions which lie between two left-going + edges) as either "inside" or "outside" according to their winding number. + +When there are no left-going edges, and the event vertex is in an +"interior" region, we need to add an edge (to split the region into +monotone pieces). To do this we simply join the event vertex to the +rightmost left endpoint of the upper or lower edge of the containing +region. + +Then we process the right-going edges. This involves: + + - inserting the edges in the edge dictionary; + - computing the winding number of any newly created active regions. + We can compute this incrementally using the winding of each edge + that we cross as we walk through the dictionary. + - relinking the mesh if necessary, so that the order of these edges around + the event vertex matches the order in the dictionary; + - checking any newly adjacent edges for intersection and/or merging. + +If there are no right-going edges, again we need to add one to split +the containing region into monotone pieces. In our case it is most +convenient to add an edge to the leftmost right endpoint of either +containing edge; however we may need to change this later (see the +code for details). + + +Invariants +---------- + +These are the most important invariants maintained during the sweep. +We define a function VertLeq(v1,v2) which defines the order in which +vertices cross the sweep line, and a function EdgeLeq(e1,e2; loc) +which says whether e1 is below e2 at the sweep event location "loc". +This function is defined only at sweep event locations which lie +between the rightmost left endpoint of {e1,e2}, and the leftmost right +endpoint of {e1,e2}. + +Invariants for the Edge Dictionary. + + - Each pair of adjacent edges e2=Succ(e1) satisfies EdgeLeq(e1,e2) + at any valid location of the sweep event. + - If EdgeLeq(e2,e1) as well (at any valid sweep event), then e1 and e2 + share a common endpoint. + - For each e in the dictionary, e->Dst has been processed but not e->Org. + - Each edge e satisfies VertLeq(e->Dst,event) && VertLeq(event,e->Org) + where "event" is the current sweep line event. + - No edge e has zero length. + - No two edges have identical left and right endpoints. + +Invariants for the Mesh (the processed portion). + + - The portion of the mesh left of the sweep line is a planar graph, + ie. there is *some* way to embed it in the plane. + - No processed edge has zero length. + - No two processed vertices have identical coordinates. + - Each "inside" region is monotone, ie. can be broken into two chains + of monotonically increasing vertices according to VertLeq(v1,v2) + - a non-invariant: these chains may intersect (slightly) due to + numerical errors, but this does not affect the algorithm's operation. + +Invariants for the Sweep. + + - If a vertex has any left-going edges, then these must be in the edge + dictionary at the time the vertex is processed. + - If an edge is marked "fixUpperEdge" (it is a temporary edge introduced + by ConnectRightVertex), then it is the only right-going edge from + its associated vertex. (This says that these edges exist only + when it is necessary.) + + +Robustness +---------- + +The key to the robustness of the algorithm is maintaining the +invariants above, especially the correct ordering of the edge +dictionary. We achieve this by: + + 1. Writing the numerical computations for maximum precision rather + than maximum speed. + + 2. Making no assumptions at all about the results of the edge + intersection calculations -- for sufficiently degenerate inputs, + the computed location is not much better than a random number. + + 3. When numerical errors violate the invariants, restore them + by making *topological* changes when necessary (ie. relinking + the mesh structure). + + +Triangulation and Grouping +-------------------------- + +We finish the line sweep before doing any triangulation. This is +because even after a monotone region is complete, there can be further +changes to its vertex data because of further vertex merging. + +After triangulating all monotone regions, we want to group the +triangles into fans and strips. We do this using a greedy approach. +The triangulation itself is not optimized to reduce the number of +primitives; we just try to get a reasonable decomposition of the +computed triangulation. diff --git a/mesalib/src/glu/sgi/libtess/dict-list.h b/mesalib/src/glu/sgi/libtess/dict-list.h new file mode 100644 index 000000000..11331a76e --- /dev/null +++ b/mesalib/src/glu/sgi/libtess/dict-list.h @@ -0,0 +1,100 @@ +/* + * SGI FREE SOFTWARE LICENSE B (Version 2.0, Sept. 18, 2008) + * Copyright (C) 1991-2000 Silicon Graphics, Inc.

There is also a "next" + * pointer for the global edge list (see below). + * + * The notation used for mesh navigation: + * Sym = the mate of a half-edge (same edge, but opposite direction) + * Onext = edge CCW around origin vertex (keep same origin) + * Dnext = edge CCW around destination vertex (keep same dest) + * Lnext = edge CCW around left face (dest becomes new origin) + * Rnext = edge CCW around right face (origin becomes new dest) + * + * "prev" means to substitute CW for CCW in the definitions above. + * + * The mesh keeps global lists of all vertices, faces, and edges, + * stored as doubly-linked circular lists with a dummy header node. + * The mesh stores pointers to these dummy headers (vHead, fHead, eHead). + * + * The circular edge list is special; since half-edges always occur + * in pairs (e and e->Sym), each half-edge stores a pointer in only + * one direction. Starting at eHead and following the e->next pointers + * will visit each *edge* once (ie. e or e->Sym, but not both). + * e->Sym stores a pointer in the opposite direction, thus it is + * always true that e->Sym->next->Sym->next == e. + * + * Each vertex has a pointer to next and previous vertices in the + * circular list, and a pointer to a half-edge with this vertex as + * the origin (NULL if this is the dummy header). There is also a + * field "data" for client data. + * + * Each face has a pointer to the next and previous faces in the + * circular list, and a pointer to a half-edge with this face as + * the left face (NULL if this is the dummy header). There is also + * a field "data" for client data. + * + * Note that what we call a "face" is really a loop; faces may consist + * of more than one loop (ie. not simply connected), but there is no + * record of this in the data structure. The mesh may consist of + * several disconnected regions, so it may not be possible to visit + * the entire mesh by starting at a half-edge and traversing the edge + * structure. + * + * The mesh does NOT support isolated vertices; a vertex is deleted along + * with its last edge. Similarly when two faces are merged, one of the + * faces is deleted (see __gl_meshDelete below). For mesh operations, + * all face (loop) and vertex pointers must not be NULL. However, once + * mesh manipulation is finished, __gl_MeshZapFace can be used to delete + * faces of the mesh, one at a time. All external faces can be "zapped" + * before the mesh is returned to the client; then a NULL face indicates + * a region which is not part of the output polygon. + */ + +struct GLUvertex { + GLUvertex *next; /* next vertex (never NULL) */ + GLUvertex *prev; /* previous vertex (never NULL) */ + GLUhalfEdge *anEdge; /* a half-edge with this origin */ + void *data; /* client's data */ + + /* Internal data (keep hidden) */ + GLdouble coords[3]; /* vertex location in 3D */ + GLdouble s, t; /* projection onto the sweep plane */ + long pqHandle; /* to allow deletion from priority queue */ +}; + +struct GLUface { + GLUface *next; /* next face (never NULL) */ + GLUface *prev; /* previous face (never NULL) */ + GLUhalfEdge *anEdge; /* a half edge with this left face */ + void *data; /* room for client's data */ + + /* Internal data (keep hidden) */ + GLUface *trail; /* "stack" for conversion to strips */ + GLboolean marked; /* flag for conversion to strips */ + GLboolean inside; /* this face is in the polygon interior */ +}; + +struct GLUhalfEdge { + GLUhalfEdge *next; /* doubly-linked list (prev==Sym->next) */ + GLUhalfEdge *Sym; /* same edge, opposite direction */ + GLUhalfEdge *Onext; /* next edge CCW around origin */ + GLUhalfEdge *Lnext; /* next edge CCW around left face */ + GLUvertex *Org; /* origin vertex (Overtex too long) */ + GLUface *Lface; /* left face */ + + /* Internal data (keep hidden) */ + ActiveRegion *activeRegion; /* a region with this upper edge (sweep.c) */ + int winding; /* change in winding number when crossing + from the right face to the left face */ +}; + +#define Rface Sym->Lface +#define Dst Sym->Org + +#define Oprev Sym->Lnext +#define Lprev Onext->Sym +#define Dprev Lnext->Sym +#define Rprev Sym->Onext +#define Dnext Rprev->Sym /* 3 pointers */ +#define Rnext Oprev->Sym /* 3 pointers */ + + +struct GLUmesh { + GLUvertex vHead; /* dummy header for vertex list */ + GLUface fHead; /* dummy header for face list */ + GLUhalfEdge eHead; /* dummy header for edge list */ + GLUhalfEdge eHeadSym; /* and its symmetric counterpart */ +}; + +/* The mesh operations below have three motivations: completeness, + * convenience, and efficiency. The basic mesh operations are MakeEdge, + * Splice, and Delete. All the other edge operations can be implemented + * in terms of these. The other operations are provided for convenience + * and/or efficiency. + * + * When a face is split or a vertex is added, they are inserted into the + * global list *before* the existing vertex or face (ie. e->Org or e->Lface). + * This makes it easier to process all vertices or faces in the global lists + * without worrying about processing the same data twice. As a convenience, + * when a face is split, the "inside" flag is copied from the old face. + * Other internal data (v->data, v->activeRegion, f->data, f->marked, + * f->trail, e->winding) is set to zero. + * + * ********************** Basic Edge Operations ************************** + * + * __gl_meshMakeEdge( mesh ) creates one edge, two vertices, and a loop. + * The loop (face) consists of the two new half-edges. + * + * __gl_meshSplice( eOrg, eDst ) is the basic operation for changing the + * mesh connectivity and topology. It changes the mesh so that + * eOrg->Onext <- OLD( eDst->Onext ) + * eDst->Onext <- OLD( eOrg->Onext ) + * where OLD(...) means the value before the meshSplice operation. + * + * This can have two effects on the vertex structure: + * - if eOrg->Org != eDst->Org, the two vertices are merged together + * - if eOrg->Org == eDst->Org, the origin is split into two vertices + * In both cases, eDst->Org is changed and eOrg->Org is untouched. + * + * Similarly (and independently) for the face structure, + * - if eOrg->Lface == eDst->Lface, one loop is split into two + * - if eOrg->Lface != eDst->Lface, two distinct loops are joined into one + * In both cases, eDst->Lface is changed and eOrg->Lface is unaffected. + * + * __gl_meshDelete( eDel ) removes the edge eDel. There are several cases: + * if (eDel->Lface != eDel->Rface), we join two loops into one; the loop + * eDel->Lface is deleted. Otherwise, we are splitting one loop into two; + * the newly created loop will contain eDel->Dst. If the deletion of eDel + * would create isolated vertices, those are deleted as well. + * + * ********************** Other Edge Operations ************************** + * + * __gl_meshAddEdgeVertex( eOrg ) creates a new edge eNew such that + * eNew == eOrg->Lnext, and eNew->Dst is a newly created vertex. + * eOrg and eNew will have the same left face. + * + * __gl_meshSplitEdge( eOrg ) splits eOrg into two edges eOrg and eNew, + * such that eNew == eOrg->Lnext. The new vertex is eOrg->Dst == eNew->Org. + * eOrg and eNew will have the same left face. + * + * __gl_meshConnect( eOrg, eDst ) creates a new edge from eOrg->Dst + * to eDst->Org, and returns the corresponding half-edge eNew. + * If eOrg->Lface == eDst->Lface, this splits one loop into two, + * and the newly created loop is eNew->Lface. Otherwise, two disjoint + * loops are merged into one, and the loop eDst->Lface is destroyed. + * + * ************************ Other Operations ***************************** + * + * __gl_meshNewMesh() creates a new mesh with no edges, no vertices, + * and no loops (what we usually call a "face"). + * + * __gl_meshUnion( mesh1, mesh2 ) forms the union of all structures in + * both meshes, and returns the new mesh (the old meshes are destroyed). + * + * __gl_meshDeleteMesh( mesh ) will free all storage for any valid mesh. + * + * __gl_meshZapFace( fZap ) destroys a face and removes it from the + * global face list. All edges of fZap will have a NULL pointer as their + * left face. Any edges which also have a NULL pointer as their right face + * are deleted entirely (along with any isolated vertices this produces). + * An entire mesh can be deleted by zapping its faces, one at a time, + * in any order. Zapped faces cannot be used in further mesh operations! + * + * __gl_meshCheckMesh( mesh ) checks a mesh for self-consistency. + */ + +GLUhalfEdge *__gl_meshMakeEdge( GLUmesh *mesh ); +int __gl_meshSplice( GLUhalfEdge *eOrg, GLUhalfEdge *eDst ); +int __gl_meshDelete( GLUhalfEdge *eDel ); + +GLUhalfEdge *__gl_meshAddEdgeVertex( GLUhalfEdge *eOrg ); +GLUhalfEdge *__gl_meshSplitEdge( GLUhalfEdge *eOrg ); +GLUhalfEdge *__gl_meshConnect( GLUhalfEdge *eOrg, GLUhalfEdge *eDst ); + +GLUmesh *__gl_meshNewMesh( void ); +GLUmesh *__gl_meshUnion( GLUmesh *mesh1, GLUmesh *mesh2 ); +void __gl_meshDeleteMesh( GLUmesh *mesh ); +void __gl_meshZapFace( GLUface *fZap ); + +#ifdef NDEBUG +#define __gl_meshCheckMesh( mesh ) +#else +void __gl_meshCheckMesh( GLUmesh *mesh ); +#endif + +#endif diff --git a/mesalib/src/glu/sgi/libtess/normal.c b/mesalib/src/glu/sgi/libtess/normal.c new file mode 100644 index 000000000..0a2494be3 --- /dev/null +++ b/mesalib/src/glu/sgi/libtess/normal.c @@ -0,0 +1,253 @@ +/* + * SGI FREE SOFTWARE LICENSE B (Version 2.0, Sept. 18, 2008) + * Copyright (C) 1991-2000 Silicon Graphics, Inc.

Input string is a stream of ASCII + characters terminated with a null-character ('\0'). Checking it using C language is + difficult and hard to implement without bugs. It is hard to maintain and make changes when + the syntax changes. + + This is because of a high redundancy of the C code. Large blocks of code are duplicated with + only small changes. Even use of macros does not solve the problem because macros cannot + erase the complexity of the problem. + + The resolution is to create a new language that will be highly oriented to our task. Once + we describe a particular syntax, we are done. We can then focus on the code that implements + the language. The size and complexity of it is relatively small than the code that directly + checks the syntax. + + First, we must implement our new language. Here, the language is implemented in C, but it + could also be implemented in any other language. The code is listed below. We must take + a good care that it is bug free. This is simple because the code is simple and clean. + + Next, we must describe the syntax of our new language in itself. Once created and checked + manually that it is correct, we can use it to check another scripts. + + Note that our new language loading code does not have to check the syntax. It is because we + assume that the script describing itself is correct, and other scripts can be syntactically + checked by the former script. The loading code must only do semantic checking which leads us to + simple resolving references. + + THE LANGUAGE + ------------ + + Here I will describe the syntax of the new language (further called "Synek"). It is mainly a + sequence of declarations terminated by a semicolon. The declaration consists of a symbol, + which is an identifier, and its definition. A definition is in turn a sequence of specifiers + connected with ".and" or ".or" operator. These operators cannot be mixed together in a one + definition. Specifier can be a symbol, string, character, character range or a special + keyword ".true" or ".false". + + On the very beginning of the script there is a declaration of a root symbol and is in the form: + .syntax <root_symbol>; + The <root_symbol> must be on of the symbols in declaration sequence. The syntax is correct if + the root symbol evaluates to true. A symbol evaluates to true if the definition associated with + the symbol evaluates to true. Definition evaluation depends on the operator used to connect + specifiers in the definition. If ".and" operator is used, definition evaluates to true if and + only if all the specifiers evaluate to true. If ".or" operator is used, definition evalutes to + true if any of the specifiers evaluates to true. If definition contains only one specifier, + it is evaluated as if it was connected with ".true" keyword by ".and" operator. + + If specifier is a ".true" keyword, it always evaluates to true. + + If specifier is a ".false" keyword, it always evaluates to false. Specifier evaluates to false + when it does not evaluate to true. + + Character range specifier is in the form: + '<first_character>' - '<second_character>' + If specifier is a character range, it evaluates to true if character in the stream is greater + or equal to <first_character> and less or equal to <second_character>. In that situation + the stream pointer is advanced to point to next character in the stream. All C-style escape + sequences are supported although trigraph sequences are not. The comparisions are performed + on 8-bit unsigned integers. + + Character specifier is in the form: + '<single_character>' + It evaluates to true if the following character range specifier evaluates to true: + '<single_character>' - '<single_character>' + + String specifier is in the form: + "<string>" + Let N be the number of characters in <string>. Let <string>[i] designate i-th character in + <string>. Then the string specifier evaluates to true if and only if for i in the range [0, N) + the following character specifier evaluates to true: + '<string>[i]' + If <string>[i] is a quotation mark, '<string>[i]' is replaced with '\<string>[i]'. + + Symbol specifier can be optionally preceded by a ".loop" keyword in the form: + .loop <symbol> (1) + where <symbol> is defined as follows: + <symbol> <definition>; (2) + Construction (1) is replaced by the following code: + <symbol$1> + and declaration (2) is replaced by the following: + <symbol$1> <symbol$2> .or .true; + <symbol$2> <symbol> .and <symbol$1>; + <symbol> <definition>; + + Synek supports also a register mechanizm. User can, in its SYN file, declare a number of + registers that can be accessed in the syn body. Each reg has its name and a default value. + The register is one byte wide. The C code can change the default value by calling + grammar_set_reg8() with grammar id, register name and a new value. As we know, each rule is + a sequence of specifiers joined with .and or .or operator. And now each specifier can be + prefixed with a condition expression in a form ".if (<reg_name> <operator> <hex_literal>)" + where <operator> can be == or !=. If the condition evaluates to false, the specifier + evaluates to .false. Otherwise it evalutes to the specifier. + + ESCAPE SEQUENCES + ---------------- + + Synek supports all escape sequences in character specifiers. The mapping table is listed below. + All occurences of the characters in the first column are replaced with the corresponding + character in the second column. + + Escape sequence Represents + ------------------------------------------------------------------------------------------------ + \a Bell (alert) + \b Backspace + \f Formfeed + \n New line + \r Carriage return + \t Horizontal tab + \v Vertical tab + \' Single quotation mark + \" Double quotation mark + \\ Backslash + \? Literal question mark + \ooo ASCII character in octal notation + \xhhh ASCII character in hexadecimal notation + ------------------------------------------------------------------------------------------------ + + RAISING ERRORS + -------------- + + Any specifier can be followed by a special construction that is executed when the specifier + evaluates to false. The construction is in the form: + .error <ERROR_TEXT> + <ERROR_TEXT> is an identifier declared earlier by error text declaration. The declaration is + in the form: + .errtext <ERROR_TEXT> "<error_desc>" + When specifier evaluates to false and this construction is present, parsing is stopped + immediately and <error_desc> is returned as a result of parsing. The error position is also + returned and it is meant as an offset from the beggining of the stream to the character that + was valid so far. Example: + + (**** syntax script ****) + + .syntax program; + .errtext MISSING_SEMICOLON "missing ';'" + program declaration .and .loop space .and ';' .error MISSING_SEMICOLON .and + .loop space .and '\0'; + declaration "declare" .and .loop space .and identifier; + space ' '; + + (**** sample code ****) + + declare foo , + + In the example above checking the sample code will result in error message "missing ';'" and + error position 12. The sample code is not correct. Note the presence of '\0' specifier to + assure that there is no code after semicolon - only spaces. + <error_desc> can optionally contain identifier surrounded by dollar signs $. In such a case, + the identifier and dollar signs are replaced by a string retrieved by invoking symbol with + the identifier name. The starting position is the error position. The lenght of the resulting + string is the position after invoking the symbol. + + PRODUCTION + ---------- + + Synek not only checks the syntax but it can also produce (emit) bytes associated with specifiers + that evaluate to true. That is, every specifier and optional error construction can be followed + by a number of emit constructions that are in the form: + .emit <parameter> + <paramater> can be a HEX number, identifier, a star * or a dollar $. HEX number is preceded by + 0x or 0X. If <parameter> is an identifier, it must be earlier declared by emit code declaration + in the form: + .emtcode <identifier> <hex_number> + + When given specifier evaluates to true, all emits associated with the specifier are output + in order they were declared. A star means that last-read character should be output instead + of constant value. Example: + + (**** syntax script ****) + + .syntax foobar; + .emtcode WORD_FOO 0x01 + .emtcode WORD_BAR 0x02 + foobar FOO .emit WORD_FOO .or BAR .emit WORD_BAR .or .true .emit 0x00; + FOO "foo" .and SPACE; + BAR "bar" .and SPACE; + SPACE ' ' .or '\0'; + + (**** sample text 1 ****) + + foo + + (**** sample text 2 ****) + + foobar + + For both samples the result will be one-element array. For first sample text it will be + value 1, for second - 0. Note that every text will be accepted because of presence of + .true as an alternative. + + Another example: + + (**** syntax script ****) + + .syntax declaration; + .emtcode VARIABLE 0x01 + declaration "declare" .and .loop space .and + identifier .emit VARIABLE .and (1) + .true .emit 0x00 .and (2) + .loop space .and ';'; + space ' ' .or '\t'; + identifier .loop id_char .emit *; (3) + id_char 'a'-'z' .or 'A'-'Z' .or '_'; + + (**** sample code ****) + + declare fubar; + + In specifier (1) symbol <identifier> is followed by .emit VARIABLE. If it evaluates to + true, VARIABLE constant and then production of the symbol is output. Specifier (2) is used + to terminate the string with null to signal when the string ends. Specifier (3) outputs + all characters that make declared identifier. The result of sample code will be the + following array: + { 1, 'f', 'u', 'b', 'a', 'r', 0 } + + If .emit is followed by dollar $, it means that current position should be output. Current + position is a 32-bit unsigned integer distance from the very beginning of the parsed string to + first character consumed by the specifier associated with the .emit instruction. Current + position is stored in the output buffer in Little-Endian convention (the lowest byte comes + first). +*/ + +#include <stdio.h> + +static void mem_free (void **); + +/* + internal error messages +*/ +static const byte *OUT_OF_MEMORY = (byte *) "internal error 1001: out of physical memory"; +static const byte *UNRESOLVED_REFERENCE = (byte *) "internal error 1002: unresolved reference '$'"; +static const byte *INVALID_GRAMMAR_ID = (byte *) "internal error 1003: invalid grammar object"; +static const byte *INVALID_REGISTER_NAME = (byte *) "internal error 1004: invalid register name: '$'"; +/*static const byte *DUPLICATE_IDENTIFIER = (byte *) "internal error 1005: identifier '$' already defined";*/ +static const byte *UNREFERENCED_IDENTIFIER =(byte *) "internal error 1006: unreferenced identifier '$'"; + +static const byte *error_message = NULL; /* points to one of the error messages above */ +static byte *error_param = NULL; /* this is inserted into error_message in place of $ */ +static int error_position = -1; + +static byte *unknown = (byte *) "???"; + +static void clear_last_error (void) +{ + /* reset error message */ + error_message = NULL; + + /* free error parameter - if error_param is a "???" don't free it - it's static */ + if (error_param != unknown) + mem_free ((void **) (void *) &error_param); + else + error_param = NULL; + + /* reset error position */ + error_position = -1; +} + +static void set_last_error (const byte *msg, byte *param, int pos) +{ + /* error message can be set only once */ + if (error_message != NULL) + { + mem_free ((void **) (void *) ¶m); + return; + } + + error_message = msg; + + /* if param is NULL, set error_param to unknown ("???") */ + /* note: do not try to strdup the "???" - it may be that we are here because of */ + /* out of memory error so strdup can fail */ + if (param != NULL) + error_param = param; + else + error_param = unknown; + + error_position = pos; +} + +/* + memory management routines +*/ +static void *mem_alloc (size_t size) +{ + void *ptr = grammar_alloc_malloc (size); + if (ptr == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return ptr; +} + +static void *mem_copy (void *dst, const void *src, size_t size) +{ + return grammar_memory_copy (dst, src, size); +} + +static void mem_free (void **ptr) +{ + grammar_alloc_free (*ptr); + *ptr = NULL; +} + +static void *mem_realloc (void *ptr, size_t old_size, size_t new_size) +{ + void *ptr2 = grammar_alloc_realloc (ptr, old_size, new_size); + if (ptr2 == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return ptr2; +} + +static byte *str_copy_n (byte *dst, const byte *src, size_t max_len) +{ + return grammar_string_copy_n (dst, src, max_len); +} + +static byte *str_duplicate (const byte *str) +{ + byte *new_str = grammar_string_duplicate (str); + if (new_str == NULL) + set_last_error (OUT_OF_MEMORY, NULL, -1); + return new_str; +} + +static int str_equal (const byte *str1, const byte *str2) +{ + return grammar_string_compare (str1, str2) == 0; +} + +static int str_equal_n (const byte *str1, const byte *str2, unsigned int n) +{ + return grammar_string_compare_n (str1, str2, n) == 0; +} + +static int +str_length (const byte *str) +{ + return (int) (grammar_string_length (str)); +} + +/* + useful macros +*/ +#define GRAMMAR_IMPLEMENT_LIST_APPEND(_Ty)\ + static void _Ty##_append (_Ty **x, _Ty *nx) {\ + while (*x) x = &(**x).next;\ + *x = nx;\ + } + +/* + string to byte map typedef +*/ +typedef struct map_byte_ +{ + byte *key; + byte data; + struct map_byte_ *next; +} map_byte; + +static void map_byte_create (map_byte **ma) +{ + *ma = (map_byte *) mem_alloc (sizeof (map_byte)); + if (*ma) + { + (**ma).key = NULL; + (**ma).data = '\0'; + (**ma).next = NULL; + } +} + +static void map_byte_destroy (map_byte **ma) +{ + if (*ma) + { + map_byte_destroy (&(**ma).next); + mem_free ((void **) &(**ma).key); + mem_free ((void **) ma); + } +} + +GRAMMAR_IMPLEMENT_LIST_APPEND(map_byte) + +/* + searches the map for the specified key, + returns pointer to the element with the specified key if it exists + returns NULL otherwise +*/ +static map_byte *map_byte_locate (map_byte **ma, const byte *key) +{ + while (*ma) + { + if (str_equal ((**ma).key, key)) + return *ma; + + ma = &(**ma).next; + } + + set_last_error (UNRESOLVED_REFERENCE, str_duplicate (key), -1); + return NULL; +} + +/* + searches the map for specified key, + if the key is matched, *data is filled with data associated with the key, + returns 0 if the key is matched, + returns 1 otherwise +*/ +static int map_byte_find (map_byte **ma, const byte *key, byte *data) +{ + map_byte *found = map_byte_locate (ma, key); + if (found != NULL) + { + *data = found->data; + + return 0; + } + + return 1; +} + +/* + regbyte context typedef + + Each regbyte consists of its name and a default value.

In general, compiler treats +// constructors and operators as ordinary functions with some exceptions. +// For example, the language does not allow functions to be called in +// constant expressions - here the exception is made to allow it. +// +// Each implementation provides its own version of this file. Each +// implementation can define the required set of operators and constructors +// in its own fashion. +// +// The extended language syntax is only present when compiling this file. +// It is implicitly included at the very beginning of the compiled shader, +// so no built-in functions can be used. +// +// To communicate with the implementation, a special extended "__asm" keyword +// is used, followed by an instruction name (any valid identifier), a +// destination variable identifier and a list of zero or more source +// variable identifiers. +// +// A variable identifier is a variable name declared earlier in the code +// (as a function parameter, local or global variable). +// +// An instruction name designates an instruction that must be exported +// by the implementation. Each instruction receives data from source +// variable identifiers and returns data in the destination variable +// identifier. +// +// It is up to the implementation how to define a particular operator +// or constructor. If it is expected to being used rarely, it can be +// defined in terms of other operators and constructors, +// for example: +// +// ivec2 __operator + (const ivec2 x, const ivec2 y) { +// return ivec2 (x[0] + y[0], x[1] + y[1]); +// } +// +// If a particular operator or constructor is expected to be used very +// often or is an atomic operation (that is, an operation that cannot be +// expressed in terms of other operations or would create a dependency +// cycle) it must be defined using one or more __asm constructs. +// +// Each implementation must define constructors for all scalar types +// (bool, float, int). There are 9 scalar-to-scalar constructors +// (including identity constructors). However, since the language +// introduces special constructors (like matrix constructor with a single +// scalar value), implementations must also implement these cases. +// The compiler provides the following algorithm when resolving a constructor: +// - try to find a constructor with a prototype matching ours, +// - if no constructor is found and this is a scalar-to-scalar constructor, +// raise an error, +// - if a constructor is found, execute it and return, +// - count the size of the constructor parameter list - if it is less than +// the size of our constructor's type, raise an error, +// - for each parameter in the list do a recursive constructor matching for +// appropriate scalar fields in the constructed variable, +// +// Each implementation must also define a set of operators that deal with +// built-in data types. +// There are four kinds of operators: +// 1) Operators that are implemented only by the compiler: "()" (function +// call), "," (sequence) and "?:" (selection). +// 2) Operators that are implemented by the compiler by expressing it in +// terms of other operators: +// - "." (field selection) - translated to subscript access, +// - "&&" (logical and) - translated to "<left_expr> ? <right_expr> : +// false", +// - "||" (logical or) - translated to "<left_expr> ? true : <right_expr>", +// 3) Operators that can be defined by the implementation and if the required +// prototype is not found, standard behaviour is used: +// - "==", "!=", "=" (equality, assignment) - compare or assign +// matching fields one-by-one; +// note that at least operators for scalar data types must be defined +// by the implementation to get it work, +// 4) All other operators not mentioned above. If no required prototype is +// found, an error is raised. An implementation must follow the language +// specification to provide all valid operator prototypes. +// + + + +//// Basic, scalar constructors/casts + +int __constructor(const float f) +{ + __asm
