NAME
       glColorPointer - define an array of colors


C SPECIFICATION
       void glColorPointer( GLint size,
			    GLenum type,
			    GLsizei stride,
			    const GLvoid *ptr )


PARAMETERS
       size    Specifies  the number of components per color. Must be 3 or 4.
	       The initial value is 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.	The initial value is GL_FLOAT.

       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. The initial value is 0.

       ptr     Specifies  a pointer to the first component of the first color
	       element in the array.

DESCRIPTION
       glColorPointer specifies the location and data  of an array  of	color
       components to use when rendering.  size specifies the number of compo-
       nents 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 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 glInterleavedArrays.)

       When a color array is specified, size, type, stride, and ptr 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,
       glDrawRangeElements, 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
       glArrayElement,	glDrawArrays,  glDrawRangeElements, 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 unde-
       fined.

       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.

ASSOCIATED GETS
       glIsEnabled with argument GL_COLOR_ARRAY
       glGet with argument GL_COLOR_ARRAY_SIZE
       glGet with argument GL_COLOR_ARRAY_TYPE
       glGet with argument GL_COLOR_ARRAY_STRIDE
       glGetPointerv with argument GL_COLOR_ARRAY_POINTER
