Real-Time Physics Simulation Forum

Hi all,

My company, RealSpace, has recently produced a simulation for Teck, to help train their vehicle operators on safety hazards. We used Bullet to power our vehicles and collisions.

The vehicle that operators are training on is a rubber-tired bulldozer: a 50,000 kg vehicle with fixed axis wheels and a two-part hinged chassis. We implemented it using two raycast vehicles, and a hinge constraint, and although we had to up the maximum suspension forces a little, Bullet was able to handle it extremely well.

You can read more, or see a video of the vehicle in action here.



I'd also like to thank everyone on the forums here who has answered my questions in the last year or so!

Awesome work!. I am learning vehicle simulation with Bullet too and its great to know that it can simulate non standard vehicles and large masses. Did you need to make changes in the source code for Bullet or were you able to directly use the stable release ?

As I mentioned, we upped the (hardcoded) maximum suspension force for the raycast vehicle, but aside from that the code is stock.
