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 cam imagine a vertex with multiple "smooth cone-like" sets of incident facets such that averaging occurs among two nonadjacent cones. But this does not seem to be a problem in practice.
