A fast, memory-efficient C++ library and CLI tool implementing quadric-based edge collapse mesh simplification to reduce triangle counts in 3D meshes. It is roughly four times faster than Meshlab and works best on watertight volumes without thin sections.

Use cases

• reduce triangle count of a 3D mesh
• decimate OBJ files for game engines
• simplify meshes in the browser via WebAssembly
• speed up mesh processing compared to Meshlab
• integrate mesh decimation into a C++ pipeline
• prepare lightweight 3D models for web viewing

When to choose

• you need very fast, memory-efficient mesh decimation
• your meshes are watertight volumes without thin sections
• you want a small, embeddable ~400-line header-only implementation
• you need a simple CLI to reduce OBJ meshes

When to avoid

• you need highest-quality simplification over raw speed
• your OBJ files contain multiple embedded objects
• your meshes have thin sections or non-watertight geometry
• you need support for many mesh file formats
