[vtkusers] how to use vtkMarchingContourFilter

[xdong at ucalgary.ca]

Hi all,

I tried to use vtkMarchingContourFilter to extract a surface frrom a stack
of tiff images. I got the following error. However vtkContourFilter works
perfectly. I am wondering whether because vtkMarchingCountourFilter is
under the patent packgae.

Do we need a license in order to use vtkMarchingCountourFilter?
