Re: [Flightgear-devel] Using native OSG 3D models - is it possible?

Hal,

 

Good to hear, well done. I hope and expect that it all works out for you.

 

We never even got close to trying AFAIKS.

GSoC sent out acceptance/rejection letters to mentoring orgs yesterday. I am
one of the Admins for an orginization that got accepted so I will be doing
GSoC paper work this week end. It takes a lot of prep work to get things
ready for GSoC so it is easy to not get things ready in time. But it would
have been great if FG had been able to leverage GSoC to get some specific
things done.
