Detailed Description

VSG extension Stores the current neighbor tolerance factor.

Specifies the tolerance value to use when default normals are computed. Specifically it determines which (other) points in the shape are close enough to influence the normal at each vertex. Setting a smaller tolerance value will select a smaller number of points and can reduce the time required for computing normals on very large, very dense geometry.

The default is 10e-5.

If the OIV_NORMGEN_TOLERANCE environment variable is set, the default is 1/OIV_NORMGEN_TOLERANCE.
