本书从图形学最基础的光栅扫描、区域填充、画直线和圆弧等算法讲起，详细介绍了线裁剪和面裁剪、凸区域裁剪和凹区域裁剪的异同，景物空间消隐算法和图像空间消隐算法的差别，具体讲述了二叉空间剖分(BSP)、八叉树等图形学中常用的数据结构。新版本增加了图形用户界面、椭圆、图像压缩和线条反走样算法等，还增加了Liang-Barsky裁剪算法和Nicholl-Lee-Nicholl裁剪算法。新版本大大扩充了可见面光线跟踪算法。在绘制这一章中新增了基于物理的光照明模型，透明效果，阴影生成，纹理映射，以及锥光束、平面光束、笔形光束和随机光线跟踪算法；详细讨论了光辐射度基础，统一颜色空间，彩色图象量化和印刷介质上的颜色重现等新内容。本书列举了90个例子，具体描述了各类算法的执行细节。这对初学者体会算法的基本原理，比较各类算法执行时的细微差别大有禅益。具备大学数学基础和高级程序设计语言知识的人均可自学本书。

-Book from the most basic graphics raster scan, area filling, drawing lines and arcs and so I start algorithm, details of the line cutting and surface cutting, cutting convex and concave regions cut regional differences and similarities, features space blanking algorithm and image space removal method of difference, specifically about the binary space partition (BSP), octree and other data structures used in graphics. The new release adds a graphical user interface, ellipse, image compression and line anti-aliasing algorithm, also increased the Liang-Barsky clipping algorithm and the Nicholl-Lee-Nicholl cutting algorithm. Greatly expanded new version of the ray tracing algorithm can be met. In this chapter, drawing new physics-based lighting models, transparent effects, shadow generation, texture mapping, and the cone beam, flat beam, pencil beam and the random ray tracing algorithm　detailed discussion of the optical radiometric base for the harmonized color Kongjian color image quanti
