The WebGLRenderingContext.stencilMaskSeparate()
method of
the WebGL API controls enabling and
disabling of front and/or back writing of individual bits in the stencil planes.
The WebGLRenderingContext.stencilMask()
method can set both, the front
and back stencil writemasks to one value at the same time.
Syntax
void gl.stencilMaskSeparate(face, mask);
Parameters
Return value
None.
Examples
gl.stencilMaskSeparate(gl.FRONT, 110101);
To get the current stencil masks, query the STENCIL_WRITEMASK
,
STENCIL_BACK_WRITEMASK
, or STENCIL_BITS
constants.
gl.getParameter(gl.STENCIL_WRITEMASK);
// 110101
gl.getParameter(gl.STENCIL_BACK_WRITEMASK);
// 110101
gl.getParameter(gl.STENCIL_BITS);
// 0
