Thank you again for the fast answer, but I am a bit confused in between!
I found this thread in the petrucci-forum:
There, akiross is calculating the following:
the right formulae is:
s(t)=0.5at² -> 10 = 0.5*10*1.4² ~ 9.8
So this is correct, of course ode isn't wrong"
This seems to mean that the values in the gravity-function don't
correspond to the values used in physics but have to be calculated
If I understand the formula above correctly, which I doubt, the
gravity would be
correct by the use of (0,0,-0.5)...
And the Ray-Car demo is new to me. Is it defined in some of the demos
submitted with ODE or do I have to download it explicitly?
