class Ifc4::IfcCartesianTransformationOperator3D : public Ifc4::IfcCartesianTransformationOperator

Definition from ISO/CD 10303-42:1992: A Cartesian transformation operator 3d defines a geometric transformation in three-dimensional space composed of translation, rotation, mirroring and uniform scaling. The list of normalized vectors u defines the columns of an orthogonal matrix T. These vectors are computed from the direction attributes axis1, axis2 and axis3 by the base axis function. If |T|= -1, the transformation includes mirroring.

NOTE: Corresponding ISO 10303 entity: cartesian_transformation_operator_3d, please refer to ISO/IS 10303-42:1994, p. 33 for the final definition of the formal standard.

HISTORY: New entity in IFC Release 2x.
