Assuming a usual perspective projection matrix, once the perspective division (by gl_Position.w) step is performed the depth loses its linearity, so gl_FragCoord.z is not linear. For a more detailed explanation read @Dreamer's answer. To revert back to linear you should perform 2 steps: Ver mais At Orthographic Projection the coordinates in the eye space are linearly mapped to normalized device coordinates.

WebReal depth in OpenGL / GLSL http://olivers.posterous.com/linear-depth-in-glsl-for-real So, many places will give you clues how to get linear depth from the OpenGL depth buffer, or visualise it, or other things. This, however, is what I believe to be the definitive answer: WebYou should try to use linear depth for the display, which after applying the projection matrix is (usually) stored in the w coordinate instead. Take that, divide by an appropriate number (depending on the scale of your game) to bring the numbers between 0 and 1 for your interesting depth and watch.

The result is a linear mapping: you are 'scaling' and applying an offset to some values so that they fit a different scale range.
