The WebGLRenderingContext.disable()
method of the WebGL API disables specific WebGL capabilities for this context.
The WebGLRenderingContext.disable()
method of the WebGL API disables specific WebGL capabilities for this context.
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. |
None (undefined
).
To check if a capability is disabled, use the WebGLRenderingContext.isEnabled()
method:
