Web9 de nov. de 2024 · This extension allows the application to use the OpenGL depth range in NDC, i.e. with depth in range [-1, 1], as opposed to Vulkan’s default of [0, 1]. The purpose of this extension is to allow efficient layering of OpenGL over Vulkan, by avoiding emulation in the pre-rasterization shader stages. This emulation, which effectively duplicates ... WebThe Rendering Pipeline is the sequence of steps that OpenGL takes when rendering objects. ... The vertex positions are transformed from clip-space to window space via the Perspective Divide and the Viewport Transform. …

Web26 de set. de 2015 · If you aren't storing the view space Z, but just the normalized, linear depth, then you should multiply v_fov_scale with your depth range (zFar - zNear) and offset the coordinate to zNear in the fragment shader.

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. There is the GL 1.0 function, glDepthRange, it does a remapping of normalized depth to window depth. For example, if you want to kill fragments from 0.5 … small marine glove box
