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
	IGESGeom_TransformationMatrix ()
void	Init (const Handle< TColStd_HArray2OfReal > &aMatrix)
	This method is used to set the fields of the class TransformationMatrix
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_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]
gp_GTrsf	Value () const
	returns the transformation matrix 4th row elements of GTrsf will always be 0, 0, 0, 1 (not defined)
