NAME fglColorPointer - define an array of colors FORTRAN SPECIFICATION SUBROUTINE fglColorPointer( INTEGER*4 size, INTEGER*4 type, INTEGER*4 stride, CHARACTER*8 pointer ) PARAMETERS size Specifies the number of components per color. Must be 3 or 4. type Specifies the data type of each color component in the array. Symbolic constants GL_BYTE, GL_UNSIGNED_BYTE, GL_SHORT, GL_UNSIGNED_SHORT, GL_INT, GL_UNSIGNED_INT, GL_FLOAT, and GL_DOUBLE are accepted. stride Specifies the byte offset between consecutive colors. If stride is 0, (the initial value), the colors are understood to be tightly packed in the array. pointer Specifies a pointer to the first component of the first color element in the array. DESCRIPTION fglColorPointer specifies the location and data format of an array of color components to use when rendering. size specifies the number of components per color, and must be 3 or 4. type specifies the data type of each color component, and stride specifies the byte stride from one color 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 color array is specified, size, type, stride, and pointer are saved as client-side state. To enable and disable the color array, call fglEnableClientState and fglDisableClientState with the argument GL_COLOR_ARRAY. If enabled, the color array is used when fglDrawArrays, fglDrawElements, or fglArrayElement is called. NOTES fglColorPointer is available only if the GL version is 1.1 or greater. The color array is initially disabled and isn't accessed when fglArrayElement, fglDrawArrays, or fglDrawElements is called. Execution of fglColorPointer 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. fglColorPointer is typically implemented on the client side. Color 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 3 or 4. GL_INVALID_ENUM is generated if type is not an accepted value. GL_INVALID_VALUE is generated if stride is negative.
