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. The eye space coordinates in the camera frustum (a … Ver mais Since the normalized device coordinates are in range (-1,-1,-1) to (1,1,1) the Z-coordinate has to be mapped to the depth buffer range [0,1]: To convert form the depth of the depth … Ver mais 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.
