Vehicle dynamics modelling

[serge3d]

I am about to choose an SDK for the accurate modelling of the dynamics of a vehicle (4 wheels, 2 axles, but possibly with a trailer).

1) Why should I go for Bullet rather than ODE for this ?

2) Is there any high-level Bullet documentation explaining the concepts in vehicle dynamics (how to model tires, wheels, suspensions, chassis, ...) ?

Thank's for your help.

It is up to you, both would probably work fine. Bullet has better collision detection, in my opinion, and it is more actively updated.

2) Is there any high-level Bullet documentation explaining the concepts in vehicle dynamics (how to model tires, wheels, suspensions, chassis, ...) ?

Not at the moment, I'm working on documentation. There is a basic raycast vehicle (see Demos/VehicleDemo), a popular simplified model for faster moving cars.

Thanks,
