ABSTRACT
<p>A family of techniques for creating intuitively informative shaded images of 4D mathematical objects is proposed. The rendering of an object in a 4D world is described by considering stepbystep how objects might be rendered into images in simpler worlds. The mathematical principles needed to compute projected images of objects and their shadows in D dimensions are outlined. The issues involved in producing shaded images of objects in four dimensions, including extending rendering from 3D to 4D, smooth shading, and specularity, are discussed. Results of rendering a Steiner surface, torus, and knotted sphere in four dimensions are presented.</p>
