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. Orthographic … Ver mais At Perspective Projection the projection matrix describes the mapping from 3D points in the world as they are seen from of a pinhole camera, to 2D points of the viewport.
