Open Inventor SGI vs TGS

Is there a big difference between SGI and TGS Open Inventor? I will developp on SGI machine, but i’v heard that TGS has faster rendering and easier axecc to p-buffers. Is the licens for comercial use of TGS expensiv? Is the same for SGI free?

Hi !

There are some interesting extra stuff in TGS, and a few things are faster, but as you said, it’s not cheap and the SGI version is free to use, the difference is not that big though I think, but it depends a little bit on what you are going to use it for…
