Detailed Description

This class represents intersections of 3D curves.

Remarks: The intersection object links to 3D curve objects but does not contain them. Calculation of the intersection is performed by a query function.

If one of the curve objects is deleted, the intersection must be recalculated.

Corresponding C++ library: TD_Ge
