WebGLRenderingContext: stencilMaskSeparate() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Note: This feature is available in Web Workers.
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
js
stencilMaskSeparate(face, mask)
Parameters
Return value
None (undefined).
Examples
js
gl.stencilMaskSeparate(gl.FRONT, 110101);
To get the current stencil masks, query the STENCIL_WRITEMASK,
STENCIL_BACK_WRITEMASK, or STENCIL_BITS constants.
js
gl.getParameter(gl.STENCIL_WRITEMASK);
// 110101
gl.getParameter(gl.STENCIL_BACK_WRITEMASK);
// 110101
gl.getParameter(gl.STENCIL_BITS);
// 0
