WebGLRenderingContext: disable() method

The WebGLRenderingContext.disable() method of the WebGL API disables specific WebGL capabilities for this context.





A GLenum specifying which WebGL capability to disable. Possible values:

Constant Description
gl.BLEND Deactivates blending of the computed fragment color values. See WebGLRenderingContext.blendFunc().
gl.CULL_FACE Deactivates culling of polygons. See WebGLRenderingContext.cullFace().
gl.DEPTH_TEST Deactivates depth comparisons and updates to the depth buffer. See WebGLRenderingContext.depthFunc().
gl.DITHER Deactivates dithering of color components before they get written to the color buffer.
gl.POLYGON_OFFSET_FILL Deactivates adding an offset to depth values of polygon's fragments. See WebGLRenderingContext.polygonOffset().
gl.SAMPLE_ALPHA_TO_COVERAGE Deactivates the computation of a temporary coverage value determined by the alpha value.
gl.SAMPLE_COVERAGE Deactivates ANDing the fragment's coverage with the temporary coverage value. See WebGLRenderingContext.sampleCoverage().
gl.SCISSOR_TEST Deactivates the scissor test that discards fragments that are outside of the scissor rectangle. See WebGLRenderingContext.scissor().
gl.STENCIL_TEST Deactivates stencil testing and updates to the stencil buffer. See WebGLRenderingContext.stencilFunc().

When using a WebGL 2 context, the following values are available additionally:

Constant Description
gl.RASTERIZER_DISCARD Deactivates that primitives are discarded immediately before the rasterization stage, but after the optional transform feedback stage. gl.clear() commands are ignored.

Return value

None (undefined).



To check if a capability is disabled, use the WebGLRenderingContext.isEnabled() method:
