Brush should support training and viewing splats using mip splatting https://niujinshuchong.github.io/mip-splatting/

This involves:

  • Calculating the compensation in the kernels
  • Calculating the compensation deriviates in the backwards kernels, matching gSplat 1.4 "antialiased" rasterization mode
  • Probably have some option to configure things. Splats trained as mip splats don't quite work with normal viewers. So when training there should be an option to disable it. When exporting a ply, write some metadata that it's using antialiased mode (does nerfstudio do this?). When reading a ply, look for this to decide the rendering mode.
