The initial value is 0. +_phead(_param2) +Specifies a pointer to the first edge flag in the array. The initial +value is zero. +.SH DESCRIPTION +_cmnd specifies the location and data format of an array of boolean edge +flags to use when rendering. _param1 specifies the byte stride from one +edge flag to the next allowing vertices and attributes +to be packed into a single array or stored in separate arrays. +(Single-array storage may be more efficient on some implementations; +see _cmnd(InterleavedArrays).) +.P +When an edge flag array is +specified, _param1 and _param2 are saved as client-side +state. +.P +To enable and disable the edge flag array, call _cmnd(EnableClientState) and +.br +_cmnd(DisableClientState) with +the argument _const(EDGE_FLAG_ARRAY). If enabled, the edge flag array is used +when _cmnd(DrawArrays), _cmnd(DrawElements), or _cmnd(ArrayElement) is called. +.P +Use _cmnd(DrawArrays) to construct a sequence of primitives (all of +the same type) +from prespecified vertex and vertex attribute arrays. +Use _cmnd(ArrayElement) to specify primitives +by indexing vertices and vertex attributes and _cmnd(DrawElements) to +construct a sequence of primitives by indexing vertices and vertex attributes. +.SH NOTES +_cmnd is available only if the GL version is 1.1 or greater. +.P +The edge flag array is initially disabled and it won't be accessed when +.br +_cmnd(ArrayElement), _cmnd(DrawElements) or _cmnd(DrawArrays) is called. +.P +Execution of _cmnd is not allowed between the execution of +_cmnd(Begin) and the corresponding execution of _cmnd(End), +but an error may or may not be generated. If no error is generated, +the operation is undefined. +.P +_cmnd is typically implemented on the client side. +.P +Edge flag array parameters are client-side state and are therefore +not saved or restored by _cmnd(PushAttrib) and _cmnd(PopAttrib). +Use _cmnd(PushClientAttrib) and +.br +_cmnd(PopClientAttrib) instead. +.SH ERRORS +_const(INVALID_ENUM) is generated if _param1 is negative. +.SH ASSOCIATED GETS +_cmnd(IsEnabled) with argument _const(EDGE_FLAG_ARRAY) +.br +_cmnd(Get) with argument _const(EDGE_FLAG_ARRAY_STRIDE) +.br +_cmnd(GetPointerv) with argument _const(EDGE_FLAG_ARRAY_POINTER) +.SH SEE ALSO +_cmnd(ArrayElement), +_cmnd(ColorPointer), +_cmnd(DrawArrays), +_cmnd(DrawElements), +_cmnd(Enable), +_cmnd(GetPointerv), +_cmnd(IndexPointer), +_cmnd(NormalPointer), +_cmnd(PopClientAttrib), +.br +_cmnd(PushClientAttrib), +_cmnd(TexCoordPointer), +_cmnd(VertexPointer) |
