Session/Category Title: Rendering




    A cone-sphere consists of two spheres, together with the part of the cylinder or cone tangent to the two spheres and lying between them. Cone-spheres can be rapidly rendered with shading, highlights, texture, or bump maps, and composited to create twisted or branched tubular structures.
