* @class vtkMatrixToLinearTransform
|
|
* @brief 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.
