MeshLib vs VTK

Decimation Performance: Complex Example

Decimate 1.1M triangles Mesh in 100 times till 11K triangles. 

Original mesh 1.1M triangles

Result – 11K Mesh with Big Holes
Decimation Time – 11 seconds

Result – Uniform mesh
Decimation Time – 4 seconds with sequential algorithm or
1 second with parallel algorithm.

What our customers say


Ruedger Rubbert

Chief Technology Officer, Brius Technologies Inc

"With MeshInspector MeshLib we were able to automate many of our workflow processes, thanks to its advanced, modern, and efficient dental and geometry oriented algorithms, covering many of our orthodontic-related tasks: CT and intraoral scan segmentation, voxel and Boolean operations, editing, aligning, visualization, inspection, and import/export of mesh objects. We use the versatile MeshInspector MeshLib API, both in production and R&D for fast prototyping and testing of our ideas."
