Re: [osg-users] VPB on a cluster of headless Linux systems
hi robert, we tried this with mesa at our latest training code. it didn't exactly work - problems cropped up mostly wrt extension features even though we had disabled most features which would require them. i didn't take the time to track down all the odd corners, given that vpb is a work in progress. and, if anyone wants exactly this feature, it's a great community effort. :) but it's good to know authoritatively that osgdem still requires a gfx context for some cases. thanks, bob On Tue, May 6, 2008 at 11:12 AM, Robert Osfield [EMAIL PROTECTED] wrote: Hi Paul, On Wed, Apr 30, 2008 at 2:06 PM, Paul Martz [EMAIL PROTECTED] wrote: Hi Robert -- I'd like to run VPB on a cluster of display-less Linux systems.
