Early computer-generated images used shaded objects that had unnaturally smooth surfaces. To produce a textured surface using the techniques discussed would require creating an excessive number of surface pieces that follow all of the complexities of the texture. An alternative to the explosion of surfaces would be to use the techniques of texture mapping. Texture mapping is a technique used to paint scanned images of a texture onto the object being modeled. Through an associated technique, called bump mapping, the appearance of the texture can be improved still further.

Ray tracing is an incredibly complex method of producing shadows, reflections, and refractions in high-quality, three-dimensionally simulated computer graphics. Ray tracing calculates the brightness, the reflectivity, and the transparency level of every object in the image. And it does this backwards. That is, it traces the rays of light back from the viewer's eye to the object from which the light was bounced off from the original light source, taking into consideration along the way any other objects the light was bounced off or refracted through .
