计算机图形在越来越多的领域得到了广泛的应用，而大多数个人计算机用户却因 缺乏基本的编程工具而不能在便宜的PC机上生成精美的计算机图形，本书旨在帮助 这些用户挖掘PC机潜在的图形设计能力，制做逼真的高质量计算机图形。 本书介绍了计算机图形学要求的向量和矩阵算术工具，讨论了光线追踪程序的生 成和使用，并给出了实际的C代码。此外，本书还对三维建模工具、提高图像质量的方 法及图形显示设备等做了介绍。(Computer graphics have been widely used in more and more fields, while most personal computer users are unable to generate fine computer graphics on cheap PC machines because of the lack of basic programming tools. This book aims to help these users to excavate the potential graphic design ability of the PC machine and make realistic high quality computing. Machine graphics. This book introduces the vector and matrix arithmetic tools required by computer graphics, discusses the generation and use of ray tracing programs, and gives the actual C code. In addition, this paper also introduces three dimensional modeling tools, methods of improving image quality and graphic display devices.)
