OpenGL allows us to modify the comparison operators it uses for the depth test. This allows us to control when OpenGL should pass or discard fragments and when to update the depth buffer. We can set the comparison operator (or depth function) by calling glDepthFunc: The function accepts several comparison … Ver mais The depth buffer contains depth values between 0.0 and 1.0 and it compares its content with the z-values of all the objects in the scene as seen … Ver mais We know that the z-value of the built-in gl_FragCoordvector in the fragment shader contains the depth value of that particular fragment. If we were to output this depth value of the … Ver mais A common visual artifact may occur when two planes or triangles are so closely aligned to each other that the depth buffer does not have enough precision to figure out which one of the … Ver mais WebNotes.
