Wow, I can't remember the last time I read a project summary with so much jargon - I literally didn't understand anything: > UE5's Nanite implementation using WebGPU. Includes the meshlet LOD hierarchy, software rasterizer and billboard impostors. Culling on both per-instance and per-meshlet basis.

Guess this really shows how much domain specific knowledge in the Computer Graphics... Yet still, this post is now ranked top 1 on HN.

  > ("software" means it runs on the CPU instead of GPU) no, in this context it means that the rasterisation algorithm is implemented in a compute kernel, rather than using the fixed hw built into the gpu. so rasterization still happens on the gpu, just using programmable blocks.
