Controls the writing of individual bits in the stencil planes.
OpenGL C bindings library: libGL.a
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 1s. |
The glStencilMask subroutine controls the writing of individual bits in the stencil planes. The least significant n bits of the Mask parameter, where n is the number of bits in the stencil buffer, specify a mask. Wherever a 1 (one) appears in the mask, the corresponding bit in the stencil buffer is made writable. Where a 0 (zero) appears, the bit is write-protected. Initially, all bits are enabled for writing.
| GL_INVALID_OPERATION | The glStencilMask subroutine is called between a call to glBegin and the corresponding call to glEnd. |
Associated gets for the glStencilMask subroutine are as follows. (See the glGet subroutine for more information.)
glGet with argument GL_STENCIL_WRITEMASK
glGet with argument GL_STENCIL_BITS.
| /usr/include/GL/gl.h | Contains C language constants, variable type definitions, and ANSI function prototypes for OpenGL. |
