交互式計算機圖形學

前言

Tthis book is an introduction to computer graphics, with an emphasis on appli-cations vrogramming. In the first edition, which was published in 1997, I notedthat in the seven years since my previous graphics text, me nelo nan expenenceo enor-mous growthma rate of growth that exceeded most people's expectations, includingmy own. In the 11 years （and four editions） since, we have seen even more changes.Feature-length computer-animated movies have proved to be commercial and artis-tic successes. The use of computer effects in movies is standard, and it is often almostimpossible to distinguish live action from computer-generated effects. Recent hard-ware has blurred the distinction between computers and game boxes. Programmablegraphics processors provide a level of flexibility in commodity systems that was notavailable in even the most expensive workstations just a few years ago.Not only have graphics capabilities increased, but costs have been reduced forboth high- and low-end workstations. Within the last few years, the cost of a graph-ics system that can generate over 100 million three-dimensional polygons per secondwith lighting and texture mapping has gone from over $100,000 to less than $1000.The availability of commodity graphics boards for personal computers has been espe-cially significant. These boards provide support for sophisticated three-dimensionalapplications, starting at about $100. On the software side, OpenGL remains the stan-dard programmer's interface both for writing application programs and developinghigh-level products for muhiplatform applications. OpenGL supports applicationsranin from hrge scientific visualizations to cell phone games.A Top-Down ApproachThese recent advances and the success of the first four editions continue to reinforcemy belief in a top-down, programming-oriented approach to introductory computergraphics. Although many computer science and engineering departments now sup-port more than one course in the subject, most students will take only a single course.Such a course is placed in the curriculum after students have already studied pro-gramming, data structures, algorithms, software engineering, and basic mathematics.A class in computer graphics allows the instructor to build on these topics in a waythat can be both informative and fun. I want these students to be programming three-dimensional applications as soon as possible. Low-level algorithms, such as those thatdraw lines or fill polygons, can be dealt with later, after students are creating graphics.
