Remarks

Compute normal at mesh vertex by weighted sum of subset of one-ring triangle normals. Can optionally weight by area, angle, or both (averaged)

Returns

the vertex normal at vertex VertIdx of Mesh.

Parameters

Parameter

Description

TriangleFilterFunc

Only one-ring triangles for which this function returns true will be included
