Changeset 3018 in orxonox.OLD for orxonox/branches/bezierTrack

Message:

orxonox/branches/bezierTrack: moved Curve to its own file. I expect this class to be bigger than I thought at the beginning:

1. Class Curve and its subclasses: a) BezierCurve b) closedBezierCurve c) Nurbs d) any other curve that might occure

this will take some time and many hours of thinking so please help

Location:
