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.
