class ShapeSet from TopOpeBRepBuild
|
|
|
|
---Purpose:
|
|
-- Auxiliary class providing an exploration of a set
|
|
-- of shapes to build faces or solids.
|
|
-- To build faces : shapes are wires, elements are edges.
|
|
-- To build solids : shapes are shells, elements are faces.
|
|
-- The ShapeSet stores a list of shapes, a list of elements
|
|
-- to start reconstructions, and a map to search neighbours.
|
|
-- The map stores the connection between elements through
|
|
-- subshapes of type <SubShapeType> given in constructor.
|
|
-- <SubShapeType> is :
|
|
-- - TopAbs_VERTEX to connect edges
|
|
-- - TopAbs_EDGE to connect faces
|
|
--
|
|
-- Signature needed by the BlockBuilder :
|
|
-- InitStartElements(me : in out)
|
|
-- MoreStartElements(me) returns Boolean;
|
|
-- NextStartElement(me : in out);

-- InitNeighbours(me : in out; S : Shape);
