[vtkusers] Problem in migrating from 32bit version of VTK to 64bit version of VTK..

[rakesh patil]

Hi Alex,

Thanks for your quick reply. Using that article as reference, I have built
VTK versions on my 64-bit machine. As mentioned, I am facing run time error
during triangulation. I am using vtkDelaunay2D for triangulation purpose.
Any idea why is this so?

Thanks

Regards
Rakesh Patil
