package PPoly
---Purpose: This package provides persistent classes to
-- handle :
--
-- * 3D triangular polyhedrons.
--
-- * 3D polygons.
--
-- * 2D polygon.

is
class Triangle;
---Purpose: A triangle is a triplet of integers (indices of
-- the nodes).
class Triangulation;
---Purpose: A Triangulation is a 3D polyhedron made of
-- triangles. It is made of a nodes which are
-- indexed. Nodes have a 3d value and a 2d value.
-- Triangles are triplet of node indices.
--
-- This is a Transient class.
class Polygon3D;
---Purpose: A Polygon3D is made of indexed nodes.
-- Nodes have a 3d value.
class Polygon2D;
---Purpose: A Polygon2D is made of indexed nodes.
-- Nodes have a 2d value.
class PolygonOnTriangulation;
---Purpose: A polygonOnTriangulation is made of node indices
-- referencing a triangulation.
class HArray1OfTriangle
instantiates HArray1 from PCollection(Triangle from PPoly);
