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
void gl.stencilMask(mask);
Parameters
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.
Return value
None.
Examples
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
