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
