* @brief map cell data to point data
|
||
|
|
*
|
||
|
|
* vtkCellDataToPointData is a filter that transforms cell data (i.e., data
|
||
|
|
* specified per cell) into point data (i.e., data specified at cell
|
||
|
|
* points). The method of transformation is based on averaging the data
|
||
|
|
* values of all cells using a particular point. Optionally, the input cell
|
||
|
|
* 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.
