WebGLRenderingContext.stencilMask()

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.

mask

A GLuint specifying a bit mask to enable or disable writing of individual bits in the stencil planes. By default, the mask is all 1.

None.

gl.stencilMask(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
