kaleidocycle

I attempt to design a kinematic kaleidocycle structure. There is a discussion before about that:

http://www.grasshopper3d.com/forum/topics/kaleidocycle-aka-rotating...

In this case we see a geometrically approach, which doesn’t works efficient, because it required knowing how they behaviors together before, and I think it is not the ‘really behaves’.

To make the structure ‘really behaves’ I tried use kangaroo and the result works very well! As you can see I simply give the 2-set reverse UForce, and then they start to rotate until they found their equilibrium. That means 90 degree rotation. I was wondering what we can do to make a endless-rotation. I am mean 360 degree or more like this:

By the way, I try to give supports which allow a horizontal movement only (Just curious how we could keep the anchor-movement horizontally and in the same layer, for example like usual supports for compression ring…). I use the AnchorXYZ, but Kangaroo-Engine seems don’t accept its output.

So maybe some one knows a better solution?

Wonderful! thanks for sharing. I'm very happy to see Kangaroo used for this, as it was exactly this sort of thing that originally motivated its development.

I've made some small adjustments to give a continuous movement using the vortex force.

For the AnchorXYZ component - it needs to go into the ForceObjects input, not the Anchors.

To get the axes for thevortex forces I also added 3 pairs of particles locked to each other in translation.
