GLCOLORMASK(3G)                                  OpenGL 3.3                                  GLCOLORMASK(3G)



NAME
       glColorMask - enable and disable writing of frame buffer color components

C SPECIFICATION
       void glColorMask(GLboolean red, GLboolean green, GLboolean blue, GLboolean alpha);

PARAMETERS
       red, green, blue, alpha
           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.

ASSOCIATED GETS
       glGet() with argument GL_COLOR_WRITEMASK
