Bubblepeople are human figure models built from overlapping spheres. They provide a softer and more realistic representation of the human body than polygon-based models, require fewer primitives, and are easier to articulate. Unfortunately, displaying a body constructed entirely of spheres by conventional rendering techniques is relatively slow. A new slicing algorithm has been implemented which significantly decreases the time required to display solid shaded Bubblepeople as polygon models within a conventional scanline renderer.
