An input surface is automatically transformed into a masonry 3D model using our algorithm. The equilibrium of the surface is represented by two planar graphs that encode the directions and magnitudes of all forces. The generated blocks are 3D-printed and assembled into a physical model of the surface that stands in compression without using glue or reinforcements.
abstract
We present a complete design pipeline that allows non-expert users to design and analyze masonry structures, without any structural knowledge. We optimize the force layouts both geometrically and topologically, finding a self-supported structure that is as close as possible to a given target surface. The generated structures are tessellated into hexagonal blocks, with a pattern that prevents sliding failure. The model can be used in physically plausible virtual environments or 3D printed and assembled without reinforcements.
