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

trueform engine

Real-time geometric processing. Arrangements, booleans, registration, remeshing, and spatial queries — at interactive speed on million-polygon meshes. Exact and robust on real-world data.

C++PythonTypeScriptWASM

Lunar workbench

Opens the trueform engine in your browser. UI controls for humans, MCP tools for models — both rendered from the same operator schemas. Connect Claude, Gemini, or Codex and operate geometry together.
