So we take z from the result of model-view transformation, negate it, divide by zFar and get a depth value which is 0.0 at the camera’s position and 1.0 at the most distant point in the scene. WebEnabling depth buffering. In order to use depth buffering, the following must occur:. The current framebuffer, whether an FBO or the default framebuffer, must have a depth buffer. Depth testing must be enabled. This is done by calling glEnable (GL_DEPTH_TEST). By default, depth testing is disabled when you create the GL context. hilldrup cab
