vtkFieldDataToAttributeDataFilter is a class that maps field data into dataset attributes. The input to this filter is any type of dataset and the output is the same dataset (geometry/topology) with new attribute data (attribute data is passed through if not replaced during filter execution).
To use this filter you must specify which field data from the input dataset to use. There are three possibilities: the cell field data, the point field data, or the field data associated with the data object superclass. Then you specify which attribute data to create: either cell attribute data or point attribute data. Finally, you must define how to construct the various attribute data types (e.g., scalars, vectors, normals, etc.) from the arrays and the components of the arrays from the field data. This is done by associating components in the input field with components making up the attribute data. For example, you would specify a scalar with three components (RGB) by assigning components from the field for the R, then G, then B values of the scalars. You may also have to specify component ranges (for each R-G-B) to make sure that the number of R, G, and B values is the same. Also, you may want to normalize the components which helps distribute the data uniformly.
This filter is often used in conjunction with vtkDataObjectToDataSetFilter. vtkDataObjectToDataSetFilter filter generates dataset topology and geometry and passes its input field data along to its output. Then this filter is used to generate the attribute data to go along with the dataset.
To create an instance of class vtkFieldDataToAttributeDataFilter, simply invoke its constructor as follows
obj = vtkFieldDataToAttributeDataFilter
