  abstract = {Sketching communicates ideas rapidly through approximate visual
              images with low overhead (pencil and paper), no need for precision
              or specialized knowledge, and ease of low-level correction and
              revision. In contrast, most 3D computer modeling systems are good
              at generating arbitrary views of precise 3D models and support
              high-level editing and revision. The SKETCH application described
              in this paper attempts to combine the advantages of each in order
              to create an environment for rapidly conceptualizing and editing
              approximate 3D scenes. To achieve this, SKETCH uses simple
              non-photorealistic rendering and a purely gestural interface based
              on simplified line drawings of primitives that allows all
              operations to be specified within the 3D world.},
