Nonphotorealistic rendering is a field in computer science in which scientists apply artistic techniques to enhance computer graphics. This paper addresses the interrogatives what, how, and why, about NPR. The discussion expands on what NPR is and what kinds of projects are being done in NPR, specifically it focuses on three issues: two large problems in NPR, simulating pen-and-ink illustration and simulating painting, and last the application of NPR to visualization. Exploring these topics thoroughly provides some specific answers to how these effects are accomplished. Throughout the paper various motivations for using NPR are revealed, including the application of NPR to visualization (as evidence of why). Our lab is interested in applying NPR techniques to visualization, so the paper concludes with some conjecture on how to verify the efficacy of this goal.
