WebOpenGL Rendering Pipeline. The Depth Test is a per-sample processing operation performed after the Fragment Shader (and sometimes before ). The Fragment 's output depth value may be tested against the depth of the sample being written to. If the test fails, the fragment is discarded.

If a texture has a depth or depth-stencil image format and has the depth comparison activated, it cannot be used with a normal sampler.Attempting to do so results in undefined behavior.
