I have a large VTK file with rectangular data, it seems Paraview cannot handle the size of the file, so it crashes and Visit navigation is extremely slow? Can anyone point me to good open source visualization software?
ParaView should be your best bet.
- I would try different versions as each behaves differently (go back as far as 3.12)
- You also need to make sure that parallel is switched on (New versions have a "Use Multi-core" checkbox in settings)
- You might need to compile your own version if you are unlucky (I had to do this once to get 64 bit headers working)
