Collision in Kangaroo2

Hey,

I'm trying to do a collision of planes using Kangaroo2.

I've done a version with spheres, where the ClampLength LowerLimit is the sum of the radii from the affected spheres, and I tried a similar principle for rectangular shapes but it did not work.

The Problem:

It's a recoursive data stream, as the generated geometry is needed to calculate the new ClampLength LowerLimits. (See sketch below)

Is there a way to do a collision of rectangular shaped planes or boxes in Kangaroo2?
I hope someone can point me into the right direction.

Thanks,
Ben

ps. not all the interconnections are shown in the sketch
