[vtkusers] dose anyone know how to convert dataset into polydata?

[gongweixue]

I want to use vtkUnstructuredGridToPolyDataFilter,but it's a abstract class.
and can you guys tell me which filter i should use?

i used a DataSetReader as an input of TableBasedClipDataSet. The Output is also DataSet, and then i want to convert DataSet to PolyData, is there any information in DataSet lost?

I will really appreciate any suggestion!
