Exact and robust
Takes meshes as they are, not as they should be.
Exact arithmeticInteger predicates. Zero floating-point error in geometric decisions.
Non-manifold tolerantHandles flaps, inconsistent winding, degenerate faces, self-intersections.
CommutativeChain operations freely on non-ideal meshes. Clean up once at the end.
Built for AI cooperation
Your model doesn't assist. It operates.
One definitionEvery operator generates UI controls and AI tools from the same schema. Automatically.
Self-describingModels browse capabilities, read constraints, call with validated parameters.
Shared sessionHuman and AI work on the same geometry, in the same workspace, at the same time.
Products
Our engine. Your product.
trueform engine
The STL for geometry. Fast and exact mesh booleans, spatial queries, arrangements, and remeshing. Easy to use, robust on real-world data.
