GMOperatorsInterfaces CATICGMTopSplineOperator

Usage: you must use this class as is. You should never derive it.

public class CATICGMTopSplineOperator

Class defining a topological operator that creates a spline body.
WARNING - If we build a spline on a support shell and part of it isn't G1 continuous, i.e. the normals to the faces aren't continous at the boundaries of the faces, the result will be unpredictable.
This operator follows the general scheme of the topological operators. For a basic use, use directly the global function CATCGMCreateTopSpline, that directly returns the resulting body. If you need to tune specific parameters, use the advanced scheme:


Constaints can be imposed on each points in the following way:
0
no constraint, neither on the tangent, nor on the curvature.
1
the direction of the tangent is imposed.
2
the tangent is imposed.
4
the tangent and the direction of the curvature are imposed.
6
the tangent and the curvature are imposed.
