* @brief Abstract class that serves as a representation for vtkTensorProbeWidget
|
||
|
|
*
|
||
|
|
* The class serves as an abstract geometrical representation for the
|
||
|
|
* vtkTensorProbeWidget. It is left to the concrete implementation to render
|
||
|
|
* the tensors as it desires. For instance,
|
||
|
|
* vtkEllipsoidTensorProbeRepresentation renders the tensors as ellipsoids.
