NAME fglEdgeFlagPointer - define an array of edge flags FORTRAN SPECIFICATION SUBROUTINE fglEdgeFlagPointer( INTEGER*4 stride, CHARACTER*8 pointer ) PARAMETERS stride Specifies the byte offset between consecutive edge flags. If stride is 0 (the initial value), the edge flags are understood to be tightly packed in the array. pointer Specifies a pointer to the first edge flag in the array. DESCRIPTION fglEdgeFlagPointer specifies the location and data format of an array of boolean edge flags to use when rendering. stride specifies the byte stride from one edge flag to the next allowing vertexes 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 fglInterleavedArrays.) When an edge flag array is specified, stride and pointer are saved as client-side state. To enable and disable the edge flag array, call fglEnableClientState and fglDisableClientState with the argument GL_EDGE_FLAG_ARRAY. If enabled, the edge flag array is used when fglDrawArrays, fglDrawElements, or fglArrayElement is called. Use fglDrawArrays to construct a sequence of primitives (all of the same type) from prespecified vertex and vertex attribute arrays. Use fglArrayElement to specify primitives by indexing vertexes and vertex attributes and fglDrawElements to construct a sequence of primitives by indexing vertexes and vertex attributes. NOTES fglEdgeFlagPointer is available only if the GL version is 1.1 or greater. The edge flag array is initially disabled and it won't be accessed when fglArrayElement, fglDrawElements or fglDrawArrays is called. Execution of fglEdgeFlagPointer is not allowed between the execution of fglBegin and the corresponding execution of fglEnd, but an error may or may not be generated. If no error is generated, the operation is undefined. fglEdgeFlagPointer is typically implemented on the client side. Edge flag array parameters are client-side state and are therefore not saved or restored by fglPushAttrib and fglPopAttrib. Use fglPushClientAttrib and fglPopClientAttrib instead. ERRORS GL_INVALID_ENUM is generated if stride is negative.
