NAME
glStencilMask
- control the writing of individual bits in the stencil planes
C SPECIFICATION
void glStencilMask(
GLuint mask )
delim $$
PARAMETERS
mask
Specifies a bit mask to enable and disable writing of individual bits
in the stencil planes.
Initially, the mask is all 1's.
DESCRIPTION
glStencilMask controls the writing of individual bits in the stencil planes.
The least significant $n$ bits of mask,
where $n$ is the number of bits in the stencil buffer,
specify a mask.
Where a 1 appears in the mask,
it's possible to write to the corresponding bit in the stencil buffer.
Where a 0 appears,
the corresponding bit is write-protected.
Initially, all bits are enabled for writing.
ERRORS
GL_INVALID_OPERATION is generated if glStencilMask
is executed between the execution of glBegin
and the corresponding execution of glEnd.
ASSOCIATED GETS
glGet with argument GL_STENCIL_WRITEMASK glGet with argument GL_STENCIL_BITS
