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

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.
