Is there some algorithm that keeps details when creating mipMaps for SDF? For example group of 4 pixels when only one is above threshold will lose this pixel with bilinear and creating mipMaps with 'max' of those values will add noise. When purpose of SDF is keeping the same image in lower resolution what is the best way to downsample this image?

For generating SDF i use 8SSEDT
