# End-to-End Compressed Meshlet Rendering

## One-sentence takeaway

Keep the *same* compressed meshlet bytes in storage and in GPU memory; decompress inside the mesh shader just-in-time, with laced-wire connectivity that admits primitive-level random access.

## Why it matters here

226 is a meshlet *codec*. This CGF paper is the engine contract: one representation, no CPU decompress-then-upload, no dual resident copies. Anoptic's mesh path can stream GRID COMMAND world chunks as compressed meshlets and decode in the mesh shader on the draw that needs them — which is the bandwidth recipe 226 does not give you. Laced wires avoid vertex duplication while staying parallel-decodeable; task shaders can cull at meshlet granularity without inflating the uncompressed working set.

## Key ideas

- Identical compressed format on disk and in VRAM; mesh-shader decode is the geometry stage.
- Laced-wire connectivity: disjoint primitive groups, no vertex redundancy, random access at primitive grain for selective streaming and visibility.
- Bandwidth win is CPU–GPU *and* in-memory footprint; scenes that did not fit uncompressed now stay resident.
- Compare against common compressed-meshlet layouts on memory and render time.

## Caveats

- CGF 2024 vol. 43 no. 1 e15002. No arXiv. Cite 226, do not remint it.
- Decode occupancy is mesh-shader-limit bound; pair with 1129's packing guidelines rather than treating compression as a packer.
- Not Nanite virtualized geometry and not volume extraction (1032).
