Static Sub ColorMask ( Red As Boolean, Green As Boolean, Blue As Boolean, Alpha As Boolean )

Parameters

buf

For Gl.ColorMaski, 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.

Description

Gl.ColorMask and Gl.ColorMaski specify whether the individual color components in the frame buffer can or cannot be written. Gl.ColorMaski sets the mask for a specific draw buffer, whereas Gl.ColorMask sets the mask for all draw buffers. If red is Gl.FALSE, for example, no change is made to the red المكوٍّن 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.
