Description
Generalizes each part of a Polycurve into a generalized
collection of Line segments.  Generalize3D performs a
Douglas-Poiker Generalization algorithm, extended to operate in 3D
space, with a specified maximum offset tolerance, given in 3D, as
input. For Line segments, the Generalized output is a subset of the
original input vertices.  For non-Linear segments, the
Generalized output contains points along all parts of the curve,
not necessarily only the vertices.
