class ShapeIntersector from TopOpeBRep
|
|
|
|
---Purpose: Intersect two shapes.
|
|
--
|
|
-- A GeomShape is a shape with a geometric domain, i.e.
|
|
-- a Face or an Edge.
|
|
--
|
|
-- The purpose of the ShapeIntersector 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.
