This Grasshopper exercise is a special one. I used Hoopsnake components to develop the branching design I studied earlier here. This time I multiplied the number and orientations of several tree structures to generate my interpretation of the Tree of Life. The challenging part of the algorithm was to finalize every branch tangent to a predefined circle. Group 3 handles this issue by utilizing a Blend Curve component. There are many Number Sliders to play with the design. Thus, I…

This topic of trees and recursive computing is inspired by the method shown here at the Rhino Python 101 Primer. This is a beautiful method of recursion that creates tree-like shapes, composed of arcs. I constructed these arcs by using the Arc SED (start, end, direction) method. This requires start and end points and a vector that is tangent to the arc (at the start point). Therefore, the overall look of a chain of these constructions creates curves with continuous…

The design of Chinese window lattices named “ice-ray” is one of the classic studies of Shape Grammars. It is an old and good example of algorithmic design. George Stiny explained their geometric construction based on the parametric Shape Grammars approach. He explained shape rules and the abstract machine that produces the subdivisions. I was especially interested in Shape Grammars when I was a graduate student. I even made a prototype tool for Shape Grammars in MaxScript. Here is another post…

Wow! Is this possible in Grasshopper? In order to start creating recursive algorithms in Grasshopper, I finally managed to run Hoopsnake, a special component developed by Yiannis Chatzikonstantinou. This will help me develop parametric models that include loops. The fundamental experiment here shows a surface subdivision based on iterations. We should define a starting object or data, an operation to be repeated, and a limit that will tell Hoopsnake to stop looping. In this condition, this is the area of…
