We rely on volunteers to maintain many of these drivers. -Here's the current status of all included drivers: - - -Driver Status ----------------------- --------------------- -XMesa (Xlib) implements OpenGL 1.3 -OSMesa (off-screen) implements OpenGL 1.3 -FX (3dfx Voodoo1/2) implements OpenGL 1.3 -SVGA implements OpenGL 1.3 -Wind River UGL implements OpenGL 1.3 -Windows/Win32 implements OpenGL 1.3 -DOS/DJGPP implements OpenGL 1.3 -GGI implements OpenGL 1.3 -BeOS needs updating (underway) -Allegro needs updating -D3D needs updating -DOS needs updating - - - -New features in GLUT --------------------- - -1. Frames per second printing - - GLUT now looks for an environment variable called "GLUT_FPS". If it's - set, GLUT will print out a frames/second statistic to stderr when - glutSwapBuffers() is called. By default, frames/second is computed - and displayed once every 5 seconds. You can specify a different - interval (in milliseconds) when you set the env var. For example - 'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval - to one second. - - NOTE: the demo or application must call the glutInit() function for - this to work. Otherwise, the env var will be ignored. - - Finally, this feature may not be reliable in multi-window programs. - - -2. glutGetProcAddress() function - - The new function: - - void *glutGetProcAddress(const char *procName) - - is a wrapper for glXGetProcAddressARB() and wglGetProcAddress(). It - lets you dynamically get the address of an OpenGL function at runtime. - The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the - GLUT version number from 3.7 since that's probably Mark Kilgard's role. - - This function should probably also be able to return the address of - GLUT functions themselves, but it doesn't do that yet. - - - -XXX Things To Do Yet XXXX -------------------------- - -isosurf with vertex program exhibits some missing triangles (probably -when recycling the vertex buffer for long prims). - - - -Porting Info ------------- - -If you're porting a DRI or other driver from Mesa 4.0.x to Mesa 4.1 here -are some things to change: - -1. ctx->Texture._ReallyEnabled is obsolete. - - Since there are now 5 texture targets (1D, 2D, 3D, cube and rect) that - left room for only 6 units (6*5 < 32) in this field. - This field is being replaced by ctx->Texture._EnabledUnits which has one - bit per texture unit. If the bit k of _EnabledUnits is set, that means - ctx->Texture.Unit[k]._ReallyEnabled is non-zero. You'll have to look at - ctx->Texture.Unit[k]._ReallyEnabled to learn if the 1D, 2D, 3D, cube or - rect texture is enabled for unit k. - - This also means that the constants TEXTURE1_*, TEXTURE2_*, etc are - obsolete. - - The tokens TEXTURE0_* have been replaced as well (since there's no - significance to the "0" part: - - old token new token - TEXTURE0_1D TEXTURE_1D_BIT - TEXTURE0_2D TEXTURE_2D_BIT - TEXTURE0_3D TEXTURE_3D_BIT - TEXTURE0_CUBE TEXTURE_CUBE_BIT - <none> TEXTURE_RECT_BIT - - These tokens are only used for the ctx->Texture.Unit[i].Enabled and - ctx->Texture.Unit[i]._ReallyEnabled fields. Exactly 0 or 1 bits will - be set in _ReallyEnabled at any time! - - Q: "What's the purpose of Unit[i].Enabled vs Unit[i]._ReallyEnabled?" - A: The user can enable GL_TEXTURE_1D, GL_TEXTURE_2D, etc for any - texure unit all at once (an unusual thing to do). - OpenGL defines priorities that basically say GL_TEXTURE_2D has - higher priority than GL_TEXTURE_1D, etc. Also, just because a - texture target is enabled by the user doesn't mean we'll actually - use that texture! If a texture object is incomplete (missing mip- - map levels, etc) it's as if texturing is disabled for that target. - The _ReallyEnabled field will have a bit set ONLY if the texture - target is enabled and complete. This spares the driver writer from - examining a _lot_ of GL state to determine which texture target is - to be used. - - -2. Tnl tokens changes - - During the implementation of GL_NV_vertex_program some of the vertex - buffer code was changed. Specifically, the VERT_* bits defined in - tnl/t_context.h have been renamed to better match the conventions of - GL_NV_vertex_program. The old names are still present but obsolete. - Drivers should use the newer names. - - For example: VERT_RGBA is now VERT_BIT_COLOR0 and - VERT_SPEC_RGB is now VERT_BIT_COLOR1. - - - -3. Read/Draw Buffer changes - - The business of setting the current read/draw buffers in Mesa 4.0.x - was complicated. It's much simpler now in Mesa 4.1. - - Here are the changes: - - - Renamed ctx->Color.DrawDestMask to ctx->Color._DrawDestMask - - Removed ctx->Color.DriverDrawBuffer - - Removed ctx->Pixel.DriverReadBuffer - - Removed ctx->Color.MultiDrawBuffer - - Removed ctx->Driver.SetDrawBuffer() - - Removed swrast->Driver.SetReadBuffer(). - - Added ctx->Color._DrawDestMask - a bitmask of FRONT/BACK_LEFT/RIGHT_BIT - values to indicate the current draw buffers. - - Added ctx->Pixel._ReadSrcMask to indicate the source for pixel reading. - The value is _one_ of the FRONT/BACK_LEFT/RIGHT_BIT values. - - Added ctx->Driver.DrawBuffer() and ctx->Driver.ReadBuffer(). - These functions exactly correspond to glDrawBuffer and glReadBuffer calls. - Many drivers will set ctx->Driver.DrawBuffer = _swrast_DrawBuffer and - leave ctx->Draw.ReadBuffer NULL. - DRI drivers should implement their own function for ctx->Driver.DrawBuffer - and use it to set the current hardware drawing buffer. You'll probably - also want to check for GL_FRONT_AND_BACK mode and fall back to software. - Call _swrast_DrawBuffer() too, to update the swrast state. - - Added swrast->Driver.SetBuffer(). - This function should be implemented by all device drivers that use swrast. - Mesa will call it to specify the buffer to use for span reading AND - writing and point/line/triangle rendering. - There should be no confusion between current read or draw buffer anymore. - - Added swrast->CurrentBuffer to indicate which color buffer to read/draw. - Will be FRONT_LEFT_BIT, BACK_LEFT_BIT, FRONT_RIGHT_BIT or BACK_RIGHT_BIT. - This value is usually passed to swrast->Driver.SetBuffer(). - - -4. _mesa_create_context() changes. This function now takes a pointer to - a __GLimports object. The __GLimports structure contains function - pointers to system functions like fprintf(), malloc(), etc. - The _mesa_init_default_imports() function can be used to initialize - a __GLimports object. Most device drivers (like the DRI drivers) - should use this. - - -5. In tnl's struct vertex_buffer, the field "ProjectedClipCoords" - has been replaced by "NdcPtr" to better match the OpenGL spec's - terminology. - - -6. Since GL_EXT_stencil_two_side has been implemented, many of the - ctx->Stencil fields are now 2-element arrays. For example, - "GLenum Ref" is now "GLenum Ref[2]" The [0] elements are the front-face - values and the [1] elements are the back-face values. - ctx->Stencil.ActiveFace is 0 or 1 to indicate the current face for - the glStencilOp/Func/Mask() functions. - ctx->Stencil.TestTwoSide controls whether or not 1 or 2-sided stenciling - is enabled. - - -7. Removed ctx->Polygon._OffsetAny. Removed ctx->Polygon.OffsetMRD. - - -8. GLfloat / GLchan changes: - - - Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4]. - ctx->Color.ClearColor is now GLfloat[4] too. - - Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan. - - ctx->Color.AlphaRef is now GLfloat. - - texObj->BorderColor is now GLfloat[4]. texObj->_BorderChan is GLchan[4]. - - This is part of an effort to remove all GLchan types from core Mesa so - that someday we can support 8, 16 and 32-bit color channels dynamically - at runtime, instead of at compile-time. - - -9. GLboolean ctx->Tranform.ClipEnabled[MAX_CLIP_PLANES] has been replaced - by GLuint ctx->Transform.ClipPlanesEnabled. The later is a bitfield. - - -10. There's a new matrix_stack type in mtypes.h used for the Modelview, - Projection, Color and Texcoord matrix stacks. - - -11. The ctx->Current.* fields have changed a lot. Now, there's a - ctx->Current.Attrib[] array for all vertex attributes which matches - the NV vertex program conventions. - - ----------------------------------------------------------------------- |
