package Geom
--- Purpose :
-- This package contains the definition of the geometric objects
-- such as point, vector, axis placement, curves, surfaces and the
-- description of the geometric transformations available for these
-- objects.
-- All these entities are defined in 3D space.
-- This package gives the possibility :
-- . to create geometric objects,
-- . to have information about them,
-- . to modify these objects.
-- This package uses the services of the package gp (Geometric
-- processor) which describes non-persistent objects for algebraic
-- calculus and basic analytic geometry. The purpose of this package
-- is to create persistent geometric objects and to read geometric
-- information about these objects. Complexes geometric algorithmes
-- are not described in this package. At construction time,
-- elementary verifications are done to verify that the objects
-- are coherents, but some verifications which require complex
-- algorithmes (for example to check that a curve has not null
-- length or does not self-intersect) must be done before the
-- construction of the geometric objects.
