trueform

Benchmarks | TS

Overview

Performance comparisons against VTK, CGAL, libigl, Coal, FCL, and nanoflann.

TrueForm enables real-time geometric operations on million-polygon meshes. On a pair of 1M-polygon meshes, boolean union completes in 28ms and intersection curve extraction in 7ms. Try it live in your browser →

The TypeScript SDK uses the same C++ core compiled to WebAssembly, so performance characteristics are identical (accounting for WASM overhead). See the C++ benchmarks for experimental setup, detailed charts, and scaling analysis.
