A side project during our workshop in Mexico City for ACADIA 2018 explored how waste and offcut material from our notch joint prototype could be re-purposed to form a small pavilion without any explicit digital design of the parts. The idea was to construct the pavilion by alternating between intuitively placing these scrap timber elements such that they approximated a surface geometry from Rhino, and reinforcing these flimsy elements with precisely fabricated parts generated from a continuously digitized model of the physical structure.
The structure was digitized by fixing small aruco markers at the desired location of the joints, tracking these in physical space using the HoloLens and then parametrically generating a spanning geometry in real time using Grasshopper. This approach generalizes well to other applications that require reinforcement or additions to an existing physical structure, so long as these requirements are within the margins of error of the tracked markers.
