Detailed Description

convert a matrix to a transform

This is a very simple class which allows a vtkMatrix4x4 to be used in place of a vtkLinearTransform or vtkAbstractTransform. For example, if you use it as a proxy between a matrix and vtkTransformPolyDataFilter then any modifications to the matrix will automatically be reflected in the output of the filter.
