Most rendering algorithms deliberately employ approximations and other short cuts out of efficiency considerations. The frequent misuse or over-expectations of such methods, far from being common coding errors, give rise to images which exhibit characteristic and easily identifiable artifacts. This paper classifies the best-known varieties; a companion set of figures is provided as an aid to their identification.
