/**

* @class vtkExtractParticlesOverTime
|
|
* @brief Extract particles that goes through a given volumic data set.
|
|
*
|
|
* vtkExtractParticlesOverTime extracts particles (points) from the first input that goes through
|
|
* the volume of the second input by iterating over time. Both inputs should be vtkDataSet objects.
|
|
* The first input should be temporal (i.e contains time steps), and the second one should be a
|
|
* volumic dataset (i.e contains 3D cells).
|
|
*
|
|
* The output is a vtkDataSet that contains points which are subsets of the first input. The points
|
|
* move over time the same way the first input does.
