Quadro it worked fine.

I am surprised. Since sales pitch are very strong.

Just one question, which from your experience you can share. I am not able
to understand the viz market. Since while comparing vtk with others, TGS
etc were not coming winner and only VTK looked best if going for long term
/ short term gains.

Specific to medical, do you think offering from TerraRecon/Voxar are better ?
What works best for any product development ?
