During a one-day workshop with the USC School of Architecture we came up with the idea of stenciling acrylic sheet with a grid of aruco markers in order be able to track a very low resolution shape of the sheet as it was heat formed. The positions of each individual marker can be tracked simultaneously in Grasshopper, allowing simple applications to be built that provide feedback to the fabricator on how much the shape of the physical sheet deviates from a digital model representing a desired end state. While limited in precision this approach provides a very simple and low cost way of forming arbitrary shapes from sheet material, and would generalize to all sorts of other materials, forming techniques and scales.
