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.
