Abstract
In a method for representing a graphic object, rays are cast through the object. The rays originate at orthogonal planes surrounding the object. The surface of the object is sampled for shape and shade attributes at points where the rays intersect the surface. The sampled shape and shade attributes of each sampled point are stored in an octree stored in the memory.
