Web7 de ago. de 2011 · OpenGL GL_LINEAR Interpolation. OpenGL provides a good interpolation method, GL_LINEAR. It interpolates nearest 4 pixels[2 pixel in X direction and 2 Pixel in Y direction] and create a smooth image comparing to the GL_NEAREST method. GL_LINEAR method interpolates both in X and Y direction. Therefore it is called Bi … 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 set OpenGL to use GL_NEAREST min/mag filtering to draw at position (x,y), place vertices from (x,y) to (x+64,y+64) use texture coordinates (0,0) -> (64/atlas_size,64/atlas_size) This is fine for drawing at native size, but NEAREST filtering gives poor results when the user draws the object at a size other than 64x64.
