Web19 de ago. de 2014 · So the correct way to make the Z-buffer linear is to write the desired depth value right into the gl_FragDepth inside the fragment shader. 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.
