* @brief A concrete implementation of vtkTensorProbeRepresentation that renders tensors as ellipoids.
|
|
*
|
|
* vtkEllipsoidTensorProbeRepresentation is a concrete implementation of
|
|
* vtkTensorProbeRepresentation. It renders tensors as ellipsoids. Locations
|
|
* between two points when probed have the tensors linearly interpolated
|
|
* from the neighboring locations on the polyline.
