GLCOLORPOINTER() GLCOLORPOINTER() NAME glColorPointer - define an array of colors C SPECIFICATION void glColorPointer( GLint size, GLenum type, GLsizei stride, const GLvoid *pointer ) delim $$ 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_UN- SIGNED_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 ele- ment in the array. DESCRIPTION glColorPointer 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 glInterleavedArrays.) 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 glEnableClientState and glDisableClientState with the argument GL_COLOR_ARRAY. If enabled, the color array is used when glDrawArrays, glDrawElements, or glArrayElement is called. NOTES glColorPointer is available only if the GL version is 1.1 or greater. The color array is initially disabled and isn't accessed when glArrayEle- ment, glDrawArrays, or glDrawElements is called. Execution of glColorPointer is not allowed between the execution of glBegin and the corresponding execution of glEnd, but an error may or may not be generated. If no error is generated, the operation is undefined. glColorPointer is typically implemented on the client side. Color array parameters are client-side state and are therefore not saved or restored by glPushAttrib and glPopAttrib. Use glPushClientAttrib and glPopClientAttrib 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.
