We build software for meshes, point clouds and volumes — the data your scanners, CT machines and CAD systems produce every day. Two products, one engine:
| 🧩 MeshLib | The SDK. Mesh boolean, repair, simplification, offset, point cloud triangulation, ICP and voxel processing for C++, C, C#, Python and JavaScript/WebAssembly. | Try the live demo · meshlib.io |
| 🔍 MeshInspector | The application. An STL editor, viewer and mesh repair tool for 3D scans and 3D printing — on your desktop or in a browser tab. | Open the web app · meshinspector.com |
MeshInspector is built entirely on MeshLib, so the SDK is exercised every day on real production data.
- Geometry algorithms engineered to revolutionize. We help software engineers process, repair, measure and optimize 3D data with next-generation algorithms, reducing development time and costs.
- Manifold by construction. A half-edge data structure in which most non-manifold situations are simply not representable, so topology errors surface where they happen instead of three pipeline stages later.
- One engine, five languages. The same algorithms and the same results on the desktop, on a server, and in the browser.
- Measured performance. Our public boolean benchmark compares MeshLib across nine libraries on 2M-triangle models — method and data. The simplification benchmark does the same across 11 libraries.
- We use it ourselves. SmileInspector, our FDA-cleared clear-aligner platform, is built on the same engine.
- 25+ years in 3D geometry, 100+ engineers, and a support team that answers.
