WebGLRenderingContext: disable() method

Note: This feature is available in Web Workers.

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

Syntax

disable(capability)

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.

gl.disable(gl.DITHER);

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

gl.isEnabled(gl.DITHER);
// false
