-- File: TopCnx.cdl -- Created: Tue Aug 11 18:08:51 1992 -- Author: Remi LEQUETTE -- ---Copyright: Matra Datavision 1992 package TopCnx ---Purpose: This algorithm provides algorithms to computes -- transitions when many interferences occurs at the -- same place on a shape. -- -- An interference is an intersection on a shape (i.e -- a vertex on an edge or an edge on a face) with -- data about the transition (how the shape is -- crossing the boundary where the intersection -- occurs). -- -- There are three algorithms to process -- interferences : -- -- * EdgeFaceTransition : To process interferences on -- an adge crossing other edges on the boundary of a -- face. -- -- * EdgeSolidTransition : To process interferences -- on an edge crossing faces and edges on the -- boundary of a solid. -- -- * FaceSolidTransition : To process interferences -- on a face crossing other faces on the boundary of -- a solid. -- -- This package relies on the TopTrans package for -- the geometric computations. uses Standard, gp, TopAbs, TopTrans is class EdgeFaceTransition; ---Purpose: Algorithm to compute cumulated transitions on an -- edge crossing the boundary of a face. end TopCnx;
