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. Web21 de dez. de 2024 · With GL_LINEAR the filter footprint is always 2x2 texels. If you scale down by 50%, your pixel footprint is also 2x2 texels, so it still works reasonably well …
