Re: [Orca-robotics-users] Help with Orca + OpenSceneGraph

Hi Victor,

In general if you email Orca questions to the mailing list (CC'd) you're more 
likely to get the right answer as the question goes out to more people.

I'm not much of an expert on 3D acceleration unfortunately.  You can use the 
command 'glxinfo' to test whether your computer is using 3D acceleration.  On 
my laptop I have an ATI graphics card, I had to install the proprietary ATI 
drivers to get 3D acceleration working (I did it via a debian package).  3D 
acceleration makes a huge difference, before I got it working orcaview3d ran 
unbearably slowly, and it was like lightning afterwards.  Beyond that I don't 
have much special knowledge sorry.

Good luck,

Alex
