AI code migration ports geometry3Sharp to TypeScript and writes new tests
rms80 · x · 2026-07-28
A code migration completed while the author watched a movie on a plane: Fable ported geometry3Sharp’s DMesh3 and Remesher to TypeScript, and the agent even wrote tests. A screenshot shows newly added test files such as DMesh3.test.ts, Remesher.test.ts, and SmallListSet.test.ts.
The poster says the generated code seems “in the ballpark,” but they can’t compare performance yet because the session used up all the tokens. The notable part is not just the port, but that the agent also created a test suite that the original project didn’t have.
