Web26 de nov. de 2024 · The linear filtering does what it's supposed to, it's just not the thing you actually want for this context. Take a sample point halfway between an occluded sample (say, depth from light = 5 vs my depth from light = 10), and a non-occluded sample (depth from light = far plane). WebGL_NEAREST will not work the same because on farest polygons you are reading data in the smaller mipmap level, wich is not the same exact data you would read from a texel fetch. There is one case where Tex2D (almost) work the same of TexelFetch: filter is GL_NEAREST you are using a incomplete mipmap pyramid with 1 level how abortions work

WebAnisotropy. Linear mipmap filtering is good; it eliminates most of the fluttering and oddities in the distance. The problem is that it replaces a lot of that fluttering with... grey. Mipmap-based filtering works reasonably well, but it tends to over-compensate. For example, take the diagonal chain of squares at the left or right of the screen.
