glStencilMask — control the front and back writing of individual bits in the stencil planes
void glStencilMask(
|
GLuint mask); |
mask
Specifies a bit mask to enable and disable writing of individual bits in the stencil planes. Initially, the mask is all 1's.
glStencilMask controls the writing of individual bits in the stencil planes.
The least significant
mask,
where
There can be two separate mask writemasks; one affects back-facing polygons, and the other
affects front-facing polygons as well as other non-polygon primitives.
glStencilMask sets both front
and back stencil writemasks to the same values. Use glStencilMaskSeparate
to set front and back stencil writemasks to different values.
glStencilMask is the same as
calling glStencilMaskSeparate
with face set to GL_FRONT_AND_BACK.
