Web/API/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
