"WebDepth Testing • Depth testing is an effective technique for hidden surface removal, and OpenGL has functions that do this behind the scenes. • This maneuver is accomplished internally by a depth buffer with storage for a depth value for every pixel on the screen. 7 1.When a pixel is drawn, it is assigned a value " - Opengles depth test

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.
