NAMEglColorMask,_glColorMaski − enable and disable writing of frame buffer color components
C SPECIFICATIONvoid glColorMask(GLboolean red, GLboolean green, GLboolean blue, GLboolean alpha); void glColorMaski(GLuint buf, GLboolean red, GLboolean green, GLboolean blue, GLboolean alpha);
PARAMETERSbuf For glColorMaski, specifies the index of the draw buffer whose color mask to set. red, green, blue, alpha Specify whether red, green, blue, and alpha are to be written into the frame buffer. The initial values are all GL_TRUE, indicating that the color components are written.
DESCRIPTIONglColorMask and glColorMaski specify whether the individual color components in the frame buffer can or cannot be written. glColorMaski sets the mask for a specific draw buffer, whereas glColorMask sets the mask for all draw buffers. 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.
