This module is used for performing a topology-preserving reduction of surface triangles.
It implements the following methods:
| Method | Description | Supported Format(s) |
|---|---|---|
| FastQuadric | Uses Sven Forstmann's method | obj |
| Quadric | Uses vtkQuadricDecimation based on the work of Garland and Heckbert who first presented the quadric error measure at Siggraph '97 "Surface Simplification Using Quadric Error Metrics" | obj, vtp |
| DecimatePro | Uses vtkDecimatePro implementing an approach similar to the algorithm originally described in "Decimation of Triangle Meshes", Proc Siggraph `92 | obj, vtp |
Notes:
- Quadric filters provide much better shaped triangles, especially when large reduction ratio is requested.
