FabObscura: Computational Design and Fabrication for Interactive Barrier-Grid Animations
summary
A computational parameterization treats barrier masks as mathematical functions, proving any valid barrier obeys seriality, periodicity, discreteness and must pass a vertical-line “function” test so units never cross. A design tool authors, visualizes, and fabricates patterns, using unit function F, thickness T, direction θ to generate straight, curved, radial, nested, and composite animations. Physical outputs include a dynamic coaster, jar lid and clock demos, fabricated with inkjet printing and a 3D-printed prototype, all reported to work under translations, rotations, and view changes.
