/mipmaps

[ChristopherBiscardi]

The mipmaps post is fine as an introductory resource, but skips a few topics. More can be written about:

near-term fixes

Images I used in the post are using Nearest sampling instead of Linear. Anisotropic forces linear through warnings, but the default for get_or_init_descriptor is nearest.

• [ ] wrapping/clamping/reflecting mipmap generation
• [ ] linear filtering for examples (bevy defaults to nearest)

longer term topics to cover

• non-power-of-two mipmaps

• mipmap scaling options

• mipmaps for textures with alpha values

  • possible reference

• mipmaps for non-color data (normal maps, etc)

• non "downscaling" use cases for mipmaps

  • blur effects (or blurry reflections)

• min/mag/mipmap filter options

it is legit to use mips with a texture where the mag filter is nearest so you get crisp squares when close and blending when far

  • linear everywhere but do a bit of fancy sampling to get AA on the hard edges - Griffin (bevy discord link)
