[vtk-developers] vtkPowerCrustSurfaceReconstruction

Hello vtk developers!

I've tentatively committed a new class for improved surface reconstruction. 
It is a port of a whole bunch of code that was, and still is, a bit of a 
mess, not to mention rather large. However, we now have decent surface 
reconstruction in VTK - it's a big improvement over the old 
vtkSurfaceReconstructionFilter. There's a test script that shows how to use 
the class.

Issues that may come up include:
- code has not been tested on every OS, we will see how it does in the 
nightlies.
- code does not always conform to VTK's high standards (but feel free to 
work through all 11K lines correcting the bracket placements...)
- expecting to see memory leaks when purify runs, will work on these.
- coverage may be quite low, there is a fair bit of code that doesn't get 
used at the moment.
- the code on which it is based is released under the GPL - I've put 
warnings in the header file that the class should not be used for 
commercial development but maybe it should go in a separate 'GPL' directory 
like the Patented classes - thoughts on this?

Rasmus helped me with some of the bugs.

All comments welcome. If it breaks everyone's build with big problems then 
I'll quietly take it away again and work on it offline.

Tim.

OK, let's add some motivation : I'd also join the "rolling over" ball and
make purring noises with Tim and Audrius :)
