Toposculpting: Computational lightpainting and wearable computational photography for abakographic user interfaces

Toposculpting is the creation of virtual objects by moving real physical objects through space to extrude patterns like beams and pipes. In one example, a method of making pipe sculptures is proposed, using a ring-shaped object moved through space. In particular, computational lightpainting is proposed as a new form of data entry, 3D object creation, or user-interface. When combined with wearable computational photography, especially by way of a true 3D time-of-flight camera system, such as the Meta Spaceglasses (extramissive spatial imaging glass manufactured by Meta-View), real physical objects are manipulated during an actual or simulated long-exposure 3D photography process.
