What's in V3

  • ESM-only build — import the ready instance from the root, or createInstance() it yourself. No CommonJS fallback.
  • Suffix-free symbol generation — gp_Pnt (not gp_Pnt_3); overloads dispatched in C++.
  • using syntax for every disposable shape — RBV containers integrate Symbol.dispose.
  • Re-architected exception channel — catch JS errors instead of opaque WebAssembly.Exception.

See CHANGELOG.md in the repo for the full release notes.

Quickstart — npm

Install libcascade, render a 60×40×20 box with a 3 mm fillet, and export GLB.
