## What it is
A C/C++ library providing algorithms to optimize triangle meshes for GPU rendering, including vertex cache optimization, overdraw reduction, simplification, and mesh compression. It also ships gltfpack, a CLI tool for optimizing glTF assets, and bindings for Rust and JavaScript.

## Use cases
- optimize meshes for faster GPU rendering
- reduce 3D model file size
- simplify high-poly meshes to lower triangle counts
- compress glTF assets for web delivery
- generate meshlets for GPU-driven rendering
- convert meshes to triangle strips
- quantize vertex attributes

## When to choose
- you need production-grade mesh processing in C/C++ or via FFI
- you want to shrink and speed up 3D assets in a game engine or renderer
- you need to optimize glTF files for web or mobile delivery

## When to avoid
- you need general-purpose image or texture compression
- you want a high-level scene graph or 3D modeling tool rather than a geometry algorithm library

## Facets
- artifact type: library
- maturity: stable
- function: graphics, compression, image-processing
- domain: graphics, gpu-computing, cross-platform
- platform: cpp, c, cross-platform, cli, wasm, rust
- tags: mesh-optimization, 3d-graphics, gltf, vertex-cache, mesh-simplification, mesh-compression, gltfpack, rendering-performance, game-development
