glStencilMask(3gl) |

glStencilMask − control the 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 $n$ 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.
