JumpStart 3D is built with these open-source libraries and fonts. Thank you to their authors.

  Source code: OCCT https://github.com/Open-Cascade-SAS/OCCT · opencascade.js https://github.com/donalffons/opencascade.js · this build's configuration https://github.com/sgenoud/replicad/tree/main/packages/replicad-opencascadejs. The engine is kept as its own file (occt-gz.wasm, or a separate block inside the single-file version), so it can be swapped for another build. The JumpStart 3D source download includes the engine files and how to rebuild the app with them.
