In the first, we attempted to create a simplified version of what G@udi would have used for his calculations of string and weights for La S@grada Famili@.
So essentially, we had a line that was cut into segments and two points at the end were used as anchor points. From there, we applied and manipulated a downward force with attributes like damping, plasticity, etc, and applied a time for the reaction to take place. It's essentially tensile stress, for those who are nerds like me and remember everything from Physics class in high school. I had a few really great teachers so that helped, too, and Physics is life!
We then tweaked the force and created a thickness for it, so it behaved more like a slinky LOL. Actually, this sort of simulation is great for say, determining properties of a bridge.
We also applied a similar force to not just a line, but to an actual plane, so it acted like a piece of material with different properties would react.
Finally, we created a whirlp00l effect, where one central axis would have everything attracted from it.
The result is the circle and the centripetal motion. Finally, we created a trail. Mine looked a bit Fib0nacci-esque LOL.
I like this stuff a LOT. It's a beautiful blend of design choices and Physics :) And these are simulations that have been used on real objects; they're not just withing a 3D programme.
