The WebGLRenderingContext.stencilMask() method of the WebGL API controls enabling and disabling of
both the front and back writing of individual bits in the stencil planes.
The WebGLRenderingContext.stencilMaskSeparate() method can set front and
back stencil writemasks to different values.
Syntax
js
stencilMask(mask)
Parameters
Return value
None (undefined).
Examples
js
gl.stencilMask(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
