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. Tony Vasile CSC Australia
