Real-Time Physics Simulation Forum

Hello,

So I have the Bullet Physics engine up and running within my application and so far all looks good.

I do have a question about gravity; in my environment gravity works 100% but it is only a linear velocity applied for it; not natural acceleration.

So it seems like things operate in slow motion.

Any way to simulate natural gravity where things speed up as they fall?

Thank you for your time.

From my experience Bullet's gravity does accelerate over time. If your framerate is good but your objects are reaching a terminal velocity very quickly then I would guess that the friction from general motion is slowing them down (I bet Bullet has a default "air friction" effect). If this is true then the mass of your objects are probably too small and they fall like feathers. Try increasing the mass of your objects to see if the "air friction" term becomes negligible.

Don't set any damping on your body and then it will simply continue accelerating.
