generic class Inter from IntCurveSurface (
TheCurve as any;
TheCurveTool as any;
TheSurface as any;
TheSurfaceTool as any)
inherits Intersection from IntCurveSurface
---Purpose: This class provides the intersections between a
-- surface S(u,v) and a curve C(w) on their natural
-- domains (S: (uo,vo)->(u1,v1)) and (C: wo->w1).
--
-- The class <Intersection from IntCurveSurface>
-- describes the methods which are used to read
-- the results.
