osgBullet (osgbullet.googlecode.com) has facilities for running the
physics simulation in a separate thread and updating transformations via
a shared memory segment.

We have an existing visual simulation that is based on Performer. We
know have to add collision detection with landmasses and the sea bottom.
I was thinking of using OpenSceneGraph to place the vehicles in the
world and use Bullet to do the actual collision detections. At this
stage I don't need any rendering but since my vehicle models are all in
OpenFlight format and I have access to some DTED Level 1 data I thought
this was the way to go.
What I am after is example programs which have the vehicles drawn at
their latitude, longitude and altitude and shows the sort of collisions
that I am after. To speed things up I am only interested certain
vehicles. I intend to have my existing program talk to the collision
detection program via shared memory so I either I need a separate thread
which deals with reading and writing to this shared memory and updating
the collision program with where the vehicles are in the world.
Any help would be most appreciated.
