Random Linear Growth – 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!

  1. To solve the self intersection, you could define for each step to create a boolean union of your cubes or whatever, then check if the centroïd of your new geometry is or is not in the volume. If not : geometry is created if yes ask for the last face randomly choosen by grasshopper in your list +1…
    The centroïds could be then used to draw the path line of your growing structure…
    By the way, it is a very nice work!…

  2. You can also think about giving the growth a direction – growing the structure based on one or some cures. You could then always analyze the t parameter and compare.
