class  Geom_BoundedCurve 
The abstract class BoundedCurve describes the common behavior of bounded curves in 3D space. A bounded curve is limited by two finite values of the parameter, termed respectively "first parameter" and "last parameter". The "first parameter" gives the "start
point" of the bounded curve, and the "last parameter" gives the "end point" of the bounded curve. The length of a bounded curve is finite. The Geom package provides three concrete classes of bounded curves: More...
