glStencilMask - control the writing of individual bits in the stencil planes
void glStencilMask( GLuint mask )
eqn not supported
- 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 $n$ 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.
GL_INVALID_OPERATION is generated
if glStencilMask is executed between the execution of glBegin and the corresponding
execution of glEnd.
