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 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.
