Detailed Description

The abstract class Geometry for 3D space is the root
class of all geometric objects from the Geom
package. It describes the common behavior of these objects when:

applying geometric transformations to objects, and
constructing objects by geometric transformation (including copying).
Warning
Only transformations which do not modify the nature
of the geometry can be applied to Geom objects: this
is the case with translations, rotations, symmetries
and scales; this is also the case with gp_Trsf
composite transformations which are used to define
the geometric transformations applied using the
Transform or Transformed functions.
Note: Geometry defines the "prototype" of the
abstract method Transform which is defined for each
concrete type of derived object. All other
transformations are implemented using the Transform method.
