# IGESGeom_TransformationMatrix Class Reference

defines IGESTransformationMatrix, Type <124> Form <0>
in package IGESGeom
The transformation matrix entity transforms three-row column
vectors by means of matrix multiplication and then a vector
addition. This entity can be considered as an "operator"
entity in that it starts with the input vector, operates on
it as described above, and produces the output vector.

## Public Member Functions

Standard_EXPORT | IGESGeom_TransformationMatrix ()
Standard_EXPORT void | Init (const Handle(TColStd_HArray2OfReal)&aMatrix)
| This method is used to set the fields of the class TransformationMatrix - aMatrix : 3 x 4 array containing elements of the transformation matrix raises exception if aMatrix is not 3 x 4 array .
Standard_EXPORT void | SetFormNumber (const Standard_Integer form)
| Changes FormNumber (indicates the Type of Transf : Transformation 0-1 or Coordinate System 10-11-12) Error if not in ranges [0-1] or [10-12] .
Standard_EXPORT Standard_Real | Data (const Standard_Integer I, const Standard_Integer J) const
| returns individual Data Errro if I not in [1-3] or J not in [1-4]
Standard_EXPORT gp_GTrsf | Value () const
| returns the transformation matrix 4th row elements of GTrsf will always be 0, 0, 0, 1 (not defined)
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const
