glColorMask(3G)						       glColorMask(3G)

NAME
       glColorMask  -  enable and disable writing of frame buffer color compo‐
       nents

SYNOPSIS
       void glColorMask(
	       GLboolean red,
	       GLboolean green,
	       GLboolean blue,
	       GLboolean alpha );

PARAMETERS
       Specify whether red, green, blue, and alpha can or  cannot  be  written
       into  the  frame buffer. The initial values are all GL_TRUE, indicating
       that the color components can be written.

DESCRIPTION
       glColorMask() specifies whether the individual color components in  the
       frame buffer can or cannot be written. If red is GL_FALSE, for example,
       no change is made to the red component of any pixel in any of the color
       buffers, regardless of the drawing operation attempted.

       Changes	to individual bits of components cannot be controlled. Rather,
       changes are either enabled or disabled for entire color components.

ERRORS
       GL_INVALID_OPERATION is generated if glColorMask() is executed  between
       the execution of glBegin() and the corresponding execution of glEnd().

ASSOCIATED GETS
       glGet() with argument GL_COLOR_WRITEMASK
       glGet() with argument GL_RGBA_MODE
