[ODE] Beginners Questions

[Jon Watte]

You seem to have posted more than one copy of that question.

The unit is "whatever strikes your fancy, and is consistent 
with your other units". I e, if you use meters and newtons, 
time will typically be seconds.

Using a variable time step is likely to lead to significant 
instability, popping, and un-rest in your simulation. Instead, 
take multiple steps when needed, as shown in:

Hi,

I have 32 cylinders. I want to push one cylinder so that other cylinders
might fall.
What is the best way to "push" it? Should I apply a Force, a Torque or
change the rotation?

Somtimes cylinders lay down in rest, partly leaking through the horizontal
plane. Any way to prevent this?

What is the unit of the timestep? What if I want to make a real-time
application.
I'm thinking of this:

	Loop
	{
		time= elapsedTime
		DoPhysics( time )
		DoRenderScene();
	}

Thanks
