You can remove a region based on your mouse click in the following manner.

vtkPolyDataConnectivityFilter fil = new vtkPolyDataConnectivityFilter();
fil.SetInput(input);
fil.SetExtractionModeToClosestPoint();
fil.SetClosestPoint(x,y,z); //x,y,z is the world coordinates based on mouse
position

vtkPolyDataMapper .... blah,blah,blah.......
.....
.
Now you have the region which is closest to the point specified extracted.
Is this what you are looking for?

	Hi,

        I need do remove a connected region from a polydata dataset. I'm
trying to use a method called "DeleteSpecifiedRegion" (from
vtkPolydataConnectivityFilter class), but I think it works with a region
Id and not with a cell or point Id (I'm not sure). How can I specify the
exact region Id to remove it?

        Thank you!

        Pierre
