GLSTENCILMASKSEPARAT(3G)					    OpenGL 3.3						  GLSTENCILMASKSEPARAT(3G)

NAME
glStencilMaskSeparate - control the front and/or back writing of individual bits in the stencil planes C SPECIFICATION
void glStencilMaskSeparate(GLenum face, GLuint mask); PARAMETERS
face Specifies whether the front and/or back stencil writemask is updated. Three symbolic constants are valid: GL_FRONT, GL_BACK, and GL_FRONT_AND_BACK. 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
glStencilMaskSeparate 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. There can be two separate mask writemasks; one affects back-facing polygons, and the other affects front-facing polygons as well as other non-polygon primitives. glStencilMask() sets both front and back stencil writemasks to the same values, as if glStencilMaskSeparate() were called with face set to GL_FRONT_AND_BACK. ERRORS
GL_INVALID_ENUM is generated if face is not one of the accepted tokens. ASSOCIATED GETS
glGet() with argument GL_STENCIL_WRITEMASK, GL_STENCIL_BACK_WRITEMASK, or GL_STENCIL_BITS SEE ALSO

NAME
glStencilMask - control the front and back 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 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. There can be two separate mask writemasks; one affects back-facing polygons, and the other affects front-facing polygons as well as other non-polygon primitives. glStencilMask() sets both front and back stencil writemasks to the same values. Use glStencilMaskSeparate() to set front and back stencil writemasks to different values. NOTES
glStencilMask() is the same as calling glStencilMaskSeparate() with face set to GL_FRONT_AND_BACK. ASSOCIATED GETS
glGet() with argument GL_STENCIL_WRITEMASK, GL_STENCIL_BACK_WRITEMASK, or GL_STENCIL_BITS SEE ALSO
