I tried to throw an example together real quick:

http://www.cmake.org/Wiki/VTK/Examples/ContoursToSurface

but it is having some issues (only one circle is appearing, etc).  If
you (or someone else) wants to fix this example, this would definitely
be the first place to start. If you can get it to work with controlled
data, then we'll move on to why your data is not working properly.

Thanks,

David
