Must be one of +_const(UNSIGNED_BYTE), _const(UNSIGNED_SHORT), or +_const(UNSIGNED_INT). +_phead(_param6) +Specifies a pointer to the location where the indices are stored. +.SH DESCRIPTION +_cmnd is a restricted form of _cmnd(DrawElements). _param1, _param2, _param3, +and _param4 match the corresponding arguments to _cmnd(DrawElements), with +the additional constraint that all values in the arrays _param4 must lie +between _param2 and _param3, inclusive. +.P +Implementations denote recommended maximum amounts of vertex and +.br +index data, +which may be queried by calling _cmnd(Get) with argument +_const(MAX_ELEMENTS_VERTICES) and _const(MAX_ELEMENTS_INDICES). +If $_eqnparam3 ~-~ _eqnparam2 ~+~ 1$ is greater than the value of +_const(MAX_ELEMENTS_VERTICES), or if _param4 is greater than the value of +_const(MAX_ELEMENTS_INDICES), then the call may operate at reduced +performance. There is no requirement that all vertices in the range +[_param2,\ _param3] be referenced. However, the implementation may +partially process unused vertices, reducing performance from what could +be achieved with an optimal index set. +.P +When _cmnd is called, it uses _param2 sequential elements from an +enabled array, starting at _param4 to construct a sequence of +geometric primitives. _param1 specifies what kind of primitives are +constructed, and how the array elements construct these primitives. If +more than one array is enabled, each is used. If +_const(VERTEX_ARRAY) is not enabled, no geometric primitives are +constructed. +.P +Vertex attributes that are modified by _cmnd have an +unspecified value after _cmnd returns. For example, if +_const(COLOR_ARRAY) is enabled, the value of the current color is +undefined after _cmnd executes. Attributes that aren't +modified maintain their previous values. +.SH NOTES +_cmnd is available only if the GL version is 1.2 or greater. +.P +_cmnd is included in display lists. If _cmnd is entered into a +display list, +the necessary array data (determined by the array pointers and +enables) is also +entered into the display list. Because the array pointers and +enables are client-side state, their values affect display lists +when the lists are created, not when the lists are executed. +.SH ERRORS +It is an error for indices to lie outside the range [_param2,\ _param3], +but implementations may not check for this situation. Such indices +cause implementation-dependent behavior. +.P +_const(INVALID_ENUM) is generated if _param1 is not an accepted value. +.P +_const(INVALID_VALUE) is generated if _param4 is negative. +.P +_const(INVALID_VALUE) is generated if _param3 $<$ _param2. +.P +_const(INVALID_OPERATION) is generated if _cmnd is executed between +the execution of _cmnd(Begin) and the corresponding _cmnd(End). +.SH ASSOCIATED GETS +_cmnd(Get) with argument _const(MAX_ELEMENTS_VERTICES) +.P +_cmnd(Get) with argument _const(MAX_ELEMENTS_INDICES) +.SH SEE ALSO +_cmnd(ArrayElement), +_cmnd(ColorPointer), +_cmnd(DrawArrays), +_cmnd(DrawElements), +_cmnd(EdgeFlagPointer), +_cmnd(GetPointerv), +_cmnd(IndexPointer), +_cmnd(InterleavedArrays), +_cmnd(NormalPointer), +_cmnd(TexCoordPointer), +_cmnd(VertexPointer) |
