buildAverageNormals MethodStatic
- At each vertex of the mesh:
- Find clusters of almost parallel normals.
- Compute simple average of those normals.
- Index to the averages.
- For typical meshes, this correctly clusters adjacent normals.
- One can imagine a vertex with multiple "smooth cone-like" sets of adjacent facets such that averaging occurs among two nonadjacent cones. But this does not seem to be a problem in practice.
buildAverageNormals(polyface: IndexedPolyface, toleranceAngle: Angle = ...): void
| Parameter | Type | Description |
