WebGL_LINEAR_MIPMAP_NEAREST: takes the nearest mipmap level and samples that level using linear interpolation. GL_NEAREST_MIPMAP_LINEAR: linearly interpolates between the two … WebLinear filtering requires more work than nearest neighbor filtering but often is worth the extra overhead. On today’s commodity hardware, the extra cost of linear filtering is approximately zero. Linear filtering works not by taking the nearest texel to the texture coordinate, but rather by applying the weighted average of the texels surrounding the … bitch\u0027s 0w
