## What it is
A browser-based implementation of Unreal Engine 5's Nanite virtualized geometry system using WebGPU, written in TypeScript. It includes a meshlet LOD hierarchy, software rasterizer, billboard impostors, and per-instance/per-meshlet frustum and occlusion culling.

## Use cases
- render massive triangle-count 3D scenes in the browser
- learn how Nanite virtualized geometry works
- experiment with software rasterization in WebGPU compute shaders
- demo meshlet LOD hierarchies and occlusion culling
- run high-poly 3D model demos offline with Deno

## When to choose
- you want to render scenes with hundreds of millions or billions of triangles in Chrome
- you are studying or researching GPU-driven rendering and LOD techniques
- you need a reference implementation of Nanite-style meshlets and impostors on the web

## When to avoid
- you need cross-browser support - WebGPU here only works in Chrome
- you need a production game engine rather than a technical demo
- your target users are on browsers or devices without WebGPU support
