Recursive Protocols

This was an exercise in scripting a fine balance between the high levels of complexity generated by recursive logic and the relatively lower levels of complexity necessitated by fabrication methods. Recursive logic coupled with curated curves, sets the stage for multiple branching structures to “interact” with each other in an attempt to lend stability and facilitate growth. This attempt, currently semi automated, informs the next step in complete automation that will negate prescribing curves. Shown here are diagrams representing the outputs from scripting recursive protocols and fabricating partial mockup of the structure.
