Growth using Hoopsnake

This example shows an animation of my ‘work-in-progress Grasshopper definition that uses Hoopsnake to recursively perform a ‘copy by mirror’ function on a geometric form. The two examples are based on a cube and a tetrahedron. The growth is linear; expanding by one module with each step. The position of each new module is determined by a new randomly selected face of the preceding module.

I would like to develop the definition so that it doesn’t self intersect, so any comments with ideas on how to achieve this would be appreciated!

hello dan,

do you found a solution for your problem? im very interessted in your work. i try to find a solution for 3 days now...

i check if points of the new tedrahedon are inside the historygeometry. then i cull the last result. after this the growingprocess always starts at the basic tadrahedon, but i want to continue with the last one... i dont know how to solve this problem... do you have an idea?

Hi Max,

I'm glad you're interested in the definition and are trying to take it further. I progressed my project in a different direction after I got stuck on this problem, so I never worked it out... Best of luck trying though! I think that testing for inclusion like you're doing is probably the way forward.

Let me know if you manage to work it out!

All the best,

Dan

Hey! I was working on the same thing and stumbled upon this thread :)

I do have a pretty good way to avoid immediate self-ints, but unfortunately it tends to self-intersect after a few steps down the road. Here's my take on it:

)(the trick is to drop the face that you are going to use for the next tetrahedron, and record the other 2 that aren't used)
