* @brief map point data to cell data
|
||
|
|
*
|
||
|
|
* vtkPointDataToCellData is a filter that transforms point data (i.e., data
|
||
|
|
* specified per point) into cell data (i.e., data specified per cell).
|
||
|
|
* The method of transformation is based on averaging the data
|
||
|
|
* values of all points defining a particular cell. Optionally, the input point
|
||
|
|
* data can be passed through to the output as well.
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* This filter is an abstract filter, that is, the output is an abstract type
|
||
|
|
* (i.e., vtkDataSet). Use the convenience methods (e.g.,
|
||
|
|
* GetPolyDataOutput(), GetStructuredPointsOutput(), etc.) to get the type
|
||
|
|
* of output you want.
