Thanks David for your answer, Can the output of a filter be the input once modified and without a copy ? (I don't want to create a new vtkDataSet each time an operation is executed)
I'd like to handle a huge amount of data (1000^3 cubes minimum), is the IO operation can be a problem for the save to disk task of the mesh ? Cheers, Cyril.
