WebGLRenderingContext.disable

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

Syntax

void gl.disable(cap);

Parameters

cap

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.

Examples

gl.disable(gl.DITHER);

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

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