* @class vtkResampleWithDataset
|
|
* @brief sample point and cell data of a dataset on
|
|
* points from another dataset.
|
|
*
|
|
* Similar to vtkCompositeDataProbeFilter, vtkResampleWithDataset takes two
|
|
* inputs - Input and Source, and samples the point and cell values of Source
|
|
* on to the point locations of Input. The output has the same structure as
|
|
* Input but its point data have the resampled values from Source. Unlike
|
|
* vtkCompositeDataProbeFilter, this filter support composite datasets for both
|
|
* Input and Source.
