A C++ geometry library for creating and operating on manifold triangle meshes that represent solid objects, with guaranteed topologically robust output. It offers bindings for Python and JavaScript/WASM and is used by tools like OpenSCAD, Blender, and Godot.

Use cases

• perform robust boolean operations on 3d meshes
• ensure meshes are manifold for 3d printing or CAD
• compute CSG geometry in the browser via wasm
• repair non-manifold triangle meshes
• build procedural 3d modeling tools
• prepare solid meshes for manufacturing or structural analysis

When to choose

• you need guaranteed manifold output from mesh operations without edge cases
• you need fast, parallelized mesh boolean and CSG operations
• you want a geometry engine usable from C++, Python, or JavaScript/WASM

When to avoid

• you need general-purpose rendering or animation rather than solid geometry operations
• you work with point clouds or non-triangle mesh representations
• you need subdivision surfaces or sculpting-style mesh editing
