hi, i have got an terrain and want to get a car driving on it. I have calculated 4 Points which represents the 4 wheels in x,z coordinate. The y-value is the height of the terrain in the point(x,z).

now i need the rotation axis of car, represents by the heightvalues of my 4 points. But how can i get my x and z rotation? (the y-rotation is the direction angle of the car)

could somebody write down the maths i need for that?

I too am looking for realistic automotive physics. By realistic I mean taking in account hp, torque, gear ratios, suspension and what not. YES I know this is NOT on topic but I didn’t start the thread. Just a link would be nice. Thanks a lot.
