Gl.ColorMask (gb.opengl)
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 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.
