NAME fglTexCoordPointer - define an array of texture coordinates FORTRAN SPECIFICATION SUBROUTINE fglTexCoordPointer( INTEGER*4 size, INTEGER*4 type, INTEGER*4 stride, CHARACTER*8 pointer ) PARAMETERS size Specifies the number of coordinates per array element. Must be 1, 2, 3 or 4. The initial value is 4. type Specifies the data type of each texture coordinate. Symbolic constants GL_SHORT, GL_INT, GL_FLOAT, or GL_DOUBLE are accepted. The initial value is GL_FLOAT. stride Specifies the byte offset between consecutive array elements. If stride is 0, the array elements are understood to be tightly packed. The initial value is 0. pointer Specifies a pointer to the first coordinate of the first element in the array. DESCRIPTION fglTexCoordPointer specifies the location and data format of an array of texture coordinates to use when rendering. size specifies the number of coordinates per element, and must be 1, 2, 3, or 4. type specifies the data type of each texture coordinate and stride specifies the byte stride from one array element 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 a texture coordinate array is specified, size, type, stride, and pointer are saved client-side state. To enable and disable the texture coordinate array, call fglEnableClientState and fglDisableClientState with the argument GL_TEXTURE_COORD_ARRAY. If enabled, the texture coordinate 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 fglTexCoordPointer is available only if the GL version is 1.1 or greater. The texture coordinate array is initially disabled and it won't be accessed when fglArrayElement, fglDrawElements or fglDrawArrays is called. Execution of fglTexCoordPointer 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. fglTexCoordPointer is typically implemented on the client side with no protocol. The texture coordinate 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_VALUE is generated if size is not 1, 2, 3, or 4. GL_INVALID_ENUM is generated if type is not an accepted value. GL_INVALID_VALUE is generated if stride is negative.
