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. Web1 de jul. de 2024 · Luckily unity provides a method for us that takes the depth as we have it now and returns the linear depth between 0 and 1, 0 being in the camera and 1 being at the far clipping plane.

"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 " - Opengl depth clip

WebThe transform from NDC space to window space uses the current glDepthRange setting. That may be [0, 1], and that's what it is by default. But there's no rule that it must be. It can be anything you want, so long as both values are between 0 and 1. You can even reverse the near and far, using a range of [1, 0].
