Algodoo

Cool! I also learned something new about Algodoo!

Nice work.

s_noonan I challenge you!
- Make a perfectly circular (or procedurally curved) train track (maybe texture too) by your surface scripting.
So you just drag mouse from point A to point C then click between (point B)
(Okay maybe there are better ways how to determine curve )
Some approx. magic and you have a track Or something like that
I would do it myself If I knew how, you need to teach me more about surfaces, deastroyable objects etc.

How to make a perfectly circular track.
1. Make a straight track.
2. Select all the hinges.
3. Set bend = true, bendConstant = 1000.0, bendTarget = 0, and motorTorque = 1000.0 for all hinges.
4. Apply some torque to the free end of of the chain (using 2 thrusters or a motor with a low hingeConstant value).
5. Start the scene. The chain will curve with a radius inversely proportional to the applied torque.

See Cantilever Beam, Large Deflection for an example.

P.S. I tried the procedure above and the response is too slow.
