These tutorials are excellent:


<http://www.cplusplus.com/doc/tutorial/polymorphism/>There is some
additional magic to properly use inheritance in VTK, but if you are not
writing classes you won't need to worry about it. The above tutorials should
get you to understand what is going on to use VTK classes (why you can't
instantiate abstract classes, etc).

Good luck,
