[vtk-developers] vtkPowerCrustSurfaceReconstruction

[Tim Hutton]

Hey Will,

I spoke with Nina about the GPL issues - she said that there was no 
possibility of getting permission to include the code in VTK without it, 
the University of Texas aren't happy about the possibility of people 
developing commercial code using publically-funded software. This is a 
shame of course. You said before that GPL code in VTK wasn't necessarily a 
problem if it had warnings on but I understand your position. Of course if 
you want to speak to the U of T people and sort something out then that 
would be fantastic...

I agree that the code is too big and messy. I'm happy to take it offline 
until we can improve things - I will make it available on my website for 
people that want to use it as-is. Let me fix it up so it compiles in the 
continuous builds and I'll remove it before this evening.

Tim.
