This studio, the third and final in the Computing Drawing sequence, continues to explore computer programming as a design medium. This iteration obsesses over the idea of the corner. Programming, defined as the design and execution of algorithms, allows designers to tap into the science of computing in ways that more fashionable approaches to digital media (parametric modeling, for example) preclude. How programming can and should be used to conceive of architecture is a perpetually open question. Rather than immediately computing architecture, these studios begin by computing drawing, which by definition allows the human eye and mind to play a prominent role in design. Conceptions of authorship, ambiguity, and representation remain the focus of attention and criticism as the course moves from drawing to building (and back to drawing). The studio, as a community, cultivates an actionable obsession with three foundational elements of architecture: line, surface and corner. More details and student work are available on the course website.
