Opengl depth test
Weband is drawn to the back and depth bu ers. If it’s more than the existing depth bu er value, it fails the depth test, and is discarded. Modern graphics hardware can sometimes perform this depth test before running the active fragment shader, so depth-testing can have a performance bene t, too.
