Detailed Description

Intersect two shapes.

A GeomShape is a shape with a geometric domain, i.e. a Face or an Edge.

The purpose of the ShapeIntersector2d is to find couples of intersecting GeomShape in two Shapes (which can be any kind of topologies : Compound, Solid, Shell, etc... )

It is in charge of exploration of the shapes and rejection. For this it is provided with two tools :

• ShapeExplorer from TopOpeBRepTool.
• ShapeScanner from TopOpeBRep which implements bounding boxes.

Let S1,S2 the shapes sent to InitIntersection(S1,S2) method :

• S1 is always SCANNED by a ShapeScanner from TopOpeBRep.
• S2 is always EXPLORED by a ShapeExplorer from TopOpeBRepTool.
