void InternalTransformPoint(const float in[3], float out[3]) override
This will calculate the transformation without calling Update.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.

Apply the transformation to a combination of points, normals and vectors.
virtual void TransformNormals(vtkDataArray *inNms, vtkDataArray *outNms)
Apply the transformation to a series of normals, and append the results to outNms.
virtual vtkAbstractTransform * MakeTransform()=0
Make another transform of the same type.
virtual void InternalTransformVector(const float in[3], float out[3])
This will calculate the transformation without calling Update.

Apply the transformation to a series of points, and append the results to outPts. ...
virtual void InternalTransformNormal(const float in[3], float out[3])
This will calculate the transformation without calling Update.
virtual void TransformVectors(vtkDataArray *inVrs, vtkDataArray *outVrs)
