The abstract class Geometry for 3D space is the root class of all geometric objects. It describes the common behavior of these objects when: - applying geometric transformations to objects, and - constructing objects by geometric transformation (including copying). Performs the symmetrical transformation of this geometric object Rotates this geometric object at angle Ang (in radians) about axis Applies a scaling transformation on this geometric object with a center and scaling factor Applies a transformation to this geometric object Translates this geometric object Create a copy of this geometry Create a clone of this geometry with the same Tag Returns a boolean indicating whether a geometry extension of the type indicated as a string exists. Returns a boolean indicating whether a geometry extension with the name indicated as a string exists. Gets the first geometry extension of the type indicated by the string. Gets the first geometry extension of the name indicated by the string. Sets a geometry extension of the indicated type. Deletes all extensions of the indicated type. Deletes all extensions of the indicated name. Returns a list with information about the geometry extensions. Gives the tag of the geometry as string.
