After clipping and division by w, depth coordinates range from -1 to 1, corresponding to the near and far clipping planes. glDepthRange specifies a linear … WebWhen you divide by the post-projection-matrix .w, you don't get a linear depth from -1 to 1, it mostly gets bunched up near 1.0. To get linear depth you could do, instead, something akin to: float linearDepth = PSVSPosition.z / 2000.0; // if +2000 is your far plane PSColor = vec4 (vec3 (linearDepth), 1.0f); Share Improve this answer Follow

Web6 de jan. de 2024 · MinZ and MaxZ indicate the depth-ranges into which the scene will be rendered and are not used for clipping. Most applications will set these members to 0.0 and 1.0 to enable the system to render to the entire range of depth values in the depth buffer. In some cases, you can achieve special effects by using other depth ranges. Web3 de mar. de 2011 · DepthBiasClamp is a DX10 and 11 feature. It seems to be related to biasing the depth which is sort of what glPolygonOffset does. There is nothing about a "bias clamp" in glPolygonOffset.
