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