[vtkusers] Slicing a unstructured grid.

[Maurice van de Rijzen]

Dear all.

I've a dataset that consists of tetrahedra containing a scalar for each 
element.
I want to slice this dataset.
My first idea was to convert the dataset to a structured points dataset 
and slicing the new dataset. In order to do this i used 
vtkDataSetToStructuredPointsFilter and I obtained the following error

	Error in startup script: invalid command name 				   	 
"vtkDataSetToStructuredPointsFilter"
     	while executing
	"vtkDataSetToStructuredPointsFilter regular"

What am I doing wrong?

Is it also possible te slice a Unstructured Grid dataset directly?
