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.
