1、计算机图形学简介：
计算机图形学是计算机专业本科生必修的专业基础课。本课程介绍图形显示及图形表示的方法和原理。通过本课程的学习，使学生了解计算机在图形应用方面的基础原理，了解图形应用中的特殊性处理方法，进而学习和掌握计算机在图形领域应用中分析、建模、程序设计等方面知识，为问题的解决提供适宜的模型和办法。
简单地说，计算机图形学的主要研究内容就是研究如何在计算机中表示图形、以及利用计算机进行图形的计算、处理和显示的相关原理与算法。图形通常由点、线、面、体等几何元素和灰度、色彩、线型、线宽等非几何属性组成。其主要的目的是要利用计算机产生令人赏心悦目的真实感图形。为此，必须建立图形所描述的场
2、景的几何表示，再用某种光照模型，计算在假想的光源、纹理、材质属性下的光照明效果。事实上，图形学也把可以表示几何场景的曲线曲面造型技术和实体造型技术作为其主要的研究内容。计算机图形学的研究内容非常广泛，如图形硬件、图形标准、图形交互技术、光栅图形生成算法、曲线曲面造型、实体造型、真实感图形计算与显示算法、非真实感绘制，以及科学计算可视化、计算机动画、自然景物仿真、虚拟现实等。整个课程以C语言为例，通过介绍30多个算法和程序设计的例子，阐述计算机图形学的原理、方法和程序设计知识。
The computer graphics is compulsory professional class o
3、f undergraduate course for computer science. The introduction to computer graphics is an adaptation of Computer Graphics: Principles and Practice, which remains the most comprehensive and authoritative work in the field. While retaining the currency and accuracy of the larger book, this abbreviated
4、version focuses on topics essential for all beginners in computer graphics and provides expanded explanations for readers with less technical background. Worked examples have been added to illustrate concepts and techniques, and program code has been written in the C language to enhance the class's
5、usefulness.
Topic coverage includes basic graphics programming, hardware, and applications. Important algorithms are included to facilitate implementation of both 2D and 3D graphics. A separate chapter covers a simplified dialect of the 2D and 3D standard. Another chapter presents a concise overvie
6、w of interaction issues and techniques. Advanced material from the larger book has been condensed, and the mathematics needed for it has been explained carefully. The class is profusely examples with more than 30 algorithms. The result is an accessible introduction to computer graphics, crafted to provide a solid foundation for futher work in this exciting field.
