OpenSCAD (openscad-full.mjs / openscad-full.wasm in this directory; where present, openscad.mjs / openscad.wasm)

These files are OpenSCAD, compiled to WebAssembly from the Forgent3D fork of OpenSCAD (based on
upstream commit 7bbf60383, 2026-10-18). The fork adds a structured export of the evaluated model
(-o out.fgjson: the node tree at full numeric precision with source locations, and OpenSCAD's own
render of the model for the preview), prints .csg numbers at full precision, keeps assign(), child()
and polyhedron(triangles=) that upstream removed in 2026, says why a vector swizzle is undef when
that experimental feature is off, and builds with native WebAssembly exceptions and a larger stack.

There are two builds. openscad-full.* is the one the browser runs: it evaluates the file and renders it
with OpenSCAD's geometry backends (CGAL and Manifold). openscad.* leaves those backends out and only
evaluates.

Forgent3D runs OpenSCAD as a separate program, in its own Web Worker. OpenSCAD evaluates and renders
the file there; Forgent3D's own CAD kernel then builds the exact geometry from the evaluated node tree.
