BezierCurve BezierCurve.hxx cadex/Geom/BezierCurve.hxx.
Defines 3D Bezier curve.
Bezier curve is defined by control points (poles) and their weights. The following image depicts an example of a Bezier curve:
For introduction to and mathematical definition of Bezier curve please refer to external resources, for instance:
A rational Bezier curve contains an explicit vector of weights, whereas polynomial does not.
The curve degree equals number of poles minus one. Degree up to 25 is supported.
The Bezier curve is always considered non-periodic.
