glStencilMask
glStencilMask: control the writing of individual bits in the stencil planes.
C Specification
void glStencilMask(
GLuint mask)
Parameters
mask Specifies a bit mask to enable and disable writing of individual bits in
the stencil planes. Initially, the mask is all 1s.
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.
