/**
|

|
|
* @class vtkTensorProbeWidget
|
||
|
|
* @brief a widget to probe tensors on a polyline
|
||
|
|
*
|
||
|
|
* The class is used to probe tensors on a trajectory. The representation
|
||
|
|
* (vtkTensorProbeRepresentation) is free to choose its own method of
|
||
|
|
* rendering the tensors. For instance vtkEllipsoidTensorProbeRepresentation
|
||
|
|
* renders the tensors as ellipsoids. The interactions of the widget are
|
||
|
|
* controlled by the left mouse button. A left click on the tensor selects
|
||
|
|
* it. It can dragged around the trajectory to probe the tensors on it.
|
||
|
|
*
|
||
|
|
* For instance dragging the ellipsoid around with
|
||
|
|
* vtkEllipsoidTensorProbeRepresentation will manifest itself with the
|
||
|
|
* ellipsoid shape changing as needed along the trajectory.
