This idea is promising, at least from what I understand. My major concern is performance, and backward compatibility. Performance would be affected depending on which methods were made virtual  (if any) - that could be an issue. It looks like backward compatibility could be preserved. Also, several other people have requested other types of transformations, and this would fit right in.

I think what is preventing action at this point is that we all feel that additional discussion (and more details) are required. I would suggest the following - create a complete .h file for vtkGeneralTransform  - and send it around. Then we can all look and follow up with comments. At some point interested parties can fork from vtkusers.
