Fields

The class is defined by the following fields:

Entity/Object	Variable	Description
integer		Version
integer	d	Space dimension

integer	n1	First dimension of matrix of point coordinates (equal to d)
integer	n2	Second dimension of matrix point coordinates, number of points
doubles	pol	n1-by-n2 matrix of point coordinates

Description

Polygon chains are piecewise linear curves that are used as approximations of curves in the decomposition algorithm. They have an implicit parameter representation; that is, [(i − 1)(p − 1), i(p − 1)] on the ith interval in a polygon chain with p points. This is not a suitable representation because the derivatives can vary substantially along the curve.
