Algodoo

This is amazing! Keep up the good work!

yo

Very well done. I'm not sure if I agree with "the landscape is never the same" for the following reasons:

1. If I stop the scene and do an undo, and then restart, the scene is exactly the same as it was before.
2. There are no random variables in the scene.
3. The scene may repeat after some period, based on the relative speeds of the motorized hinges.

On the other hand, since Algodoo is not too accurate when running at 60 Hz, the landscape will never really be the same. Also, it might be years before the scene actually comes close to repeating. I would think that the repeat period would be the least common multiple of all the motor periods, where the motor period equals 2.0 * math.pi / motorSpeed.

you are right .. good observation.
the period is very long but it is not random.
thank you!
could you suggest a way to create a random motion on algodoo?

Algodoo has the following "rand." functions:

boolean
direction2D
normal
normal2D
un­iform01

They could be used for creating different kinds of random motion. I think that your mechanical approach is the best for the type of motion used in this scene. It would be more difficult to imitate it mathematically and I don't think the scene would show much improvement if a mathematical approach was used.

thank you!!
can I ask for clarification?
how and where should these functions be included?
Thanks again!!!

The last scene does not use random variables but could.

A terrain could be created by creating random slopes at random time intervals.

thankyou!!
