Chapter 13 Computer Graphics 13.1 Introduction To Computer Graphics 13.1.2 Design Professions such as engineering and architecture are concerned with design. Although their applications vary, most designers face similar difficulties and use similar methodologies. One of the principal characteristics of most design problems is the lack of a unique solution. Hence, the designer will examine a potential design and then will modify it, possibly many times, in an attempt to achieve a better solution. Computer graphics has become an indispensable element in this iterative process. 工程和建筑的专业人员关心设计,尽管他们的应用不同,但大多数设 计者面对相似的困难,采用了类似的方法。大多数设计问题的基本特 点之一是缺少唯一的解决方案,因此,设计者可能需要多次检查原来 的设计,修改它,以获得一个更好的解决方案。在这个重复的过程中, 计算机图形学已变成一个不可缺少的部分。 《什第机专出美语 13-8

Chapter 13 Computer Graphics 13.1 Introduction To Computer Graphics 13.1.3 Simul ati on Some of the most impressive and familiar uses of computer graphics can be classified as simulations. Video games demonstrate both the visual appeal of computer graphics and our ability to generate complex imagery in real time. The insides of an arcade game reveal state-of-the-art hardware and software Computer-generated images are also the heart of flight simulators which have become the standard method for training pilots. The savings in dollars and lives realized from use of these simulators has been enormous. The computer generated images we see on television and in movies have advanced to the point that they are almost indistinguisha ble from real-world images. 13.1.3模拟 最为人所知的计算机图形学应用可归为模拟类。视频游戏展示了计算机图形 学的视觉魅力和我们实时生成复杂图像的能力。走廊游戏的内容揭示了当前软 件和硬件的技术发展水平。计算机生成的图像是飞行模拟器的核心,已经成为 训练飞行员的标准方法,这种模拟训练大大节省了人力物力。我们在电视和电 影中看到的计算机生成的图像已经达到了到真实图像几乎无法区分的地步。139

Chapter 13 Computer Graphics 13.1 Introduction To Computer Graphics 13.1.4 User Interfaces The interface between the human and the computer has been radically altered by the use of computer graphics. Consider the electronic office. The figures in this book were produced through just such an interface. A secretary sits at a workstation, rather than at a desk equipped with a typewriter. This user has a pointing device, such as a mouse, that allows him to communicate with the workstation. The display consists of a number of icons that represent the various operations the secretary can perform. For example, there might be an icon of a mailbox that if pointed to and clicked on, causes any electronic-mail messages to appear on the screen. 计算机图形学的应用已经根本改变了人和计算机之间的界面。讨论一下电子 办公室,本书的图是由这样的界面产生的,秘书坐在工作站前,而不是备有 打字机的办公桌前,这一用户有一个指示设备(如鼠标实现他和工作站之间 的交互。显示由许多图符组成,代表秘书可进行的各种操作,例如,有一个 邮箱图符,如果指向并点击它,屏幕上将会显示电子邮件信息 第机 13-10
