Splatter

Inspired by gaussian-splatting but using a somewhat different approach to rendering.

Features

  • Correctly computes the perspective projection of ellipsoids by intersecting the bounding elliptic cone with the view plane
  • Uses the rasterizer instead of a tiled compute shader
  • Rasterizes rotated rectangles instead of axis aligned squares
  • GPU depth sorting using onesweep radix sort (except that the block sort is not WLMS because WebGPU does not support subgroup operations yet)
  • CPU depth sorting as a fallback
  • Frustum culling (optionally using stream compaction via indirect drawing)
  • File parser and progressive loading via segmentation in chunks
  • Lots of rendering configuration parameters to customize
