Training in the field of computer graphics usage is important for all engineering courses. Both in design and in production, as well as in technical marketing, graphic representations constitute an important means of expression for the engineer. In connection with the training of engineers, three directions of training can be discerned: basic principles of computer graphics, computer-aided design (CAD) systems with their design and application and employment of CAD systems as a new aid for the designer. Methodical didactic training constitutes a precondition for profitable application of the methods of computer graphics.

New computer graphic tools for transportation planners

Three interactive graphic computer programs are described which aid transportation planners in data analysis and display: (1) FLOWMAP, which enables the interactive design of flow maps at a computer graphics terminal using origin-destination data; (2) FLOGRAF, which graphically displays traffic flows along a network using color computer graphics, and (3) TRANES, a transit system analysis program that displays the number and type of potential transit users within specified access limits of transit facilities. Typical applications in transportation planning are suggested for each of the programs and recommendations are made for future enhancements. Readily available sources of data are suggested which can be tapped to provide input to the programs.     

An object-oriented approach to ray tracing image synthesis implementations

Object-oriented techniques can be applied, in a natural way, to computer graphics. Traditionally, these techniques have been used for the design of graphic user interfaces, but recently, they have been applied to other computer graphic fields. This paper presents the design of a ray-tracing rendering program. The program has been built using a class hierarchy in such a way that it is possible to modify algorithmic details without changing the class structure.     

图形设计的传统与突破

图形设计可谓源远流长,早在史前人类的祖先就开始用木炭或矿物颜料在洞穴的岩壁上作画,距今六七年前的原始石器时代我国已产生了陶器上的装饰纹样。至今,随着社会的不断发展,科学技术的猛速进步,信息时代已经到来,这时艺术与科学产生了前所未有的"婚姻联盟",由此,图形设计迈进了计算机尖端科技领域。纵观图形设计的演进,无论是远古的传统手工艺,还是现代的计算机图形艺术设计,我们都在传统中不断地突破和创新。本文将通过对图形设计的探讨对其传统与突破进行阐述,并提出本人的看法。     

A facsimile-based graphics editing system by auxiliary mark recognition

This paper describes a facsimile-based graphics editing system using handwritten mark recognition, and presents some experimental results with the system. In a manner different from usual graphics editors based on CRT displays and data tablets, only facsimiles are used as input and output devices in this system. As the first stage in processing, a graphic subject is first given as a set of line drawings and characters handwritten on a sheet of paper, and it is then input into the computer as a binary picture from a facsimile transmitter. Auxiliary editing information is input into the computer as handwritten marks or seal marks prepared on a separate sheet of paper. As the second stage, the marks are recognized and used to create a mark parameter list for the graphics editing. Third, referencing the mark parameter list, the graphics are expressed by using a set of graphic commands, and edited by the computer. Finally, a correct edited copy of the graphics is constructed by picture processing based on graphic commands, and it is output to a facsimile receiver. Very good results have been obtained for various kinds of hand-written graphics by using the system described here.     

Software for robotic simulation

The last few years have witnessed a large increase in use of computer graphics to simulate the robotic performance. The utilization of graphic simulation and programming has greatly enhanced the design, control, and productivity of robotic applications, especially in manufacturing. When designing and controlling robotic systems, computer graphics can be used to evaluate how the robot will react to and perform within the production environment before significant time, capital, and expense are incurred. Graphic simulation enables the designer not only to select the right robot but also to program it to perform the task in the most efficient way. The purpose of this paper is to review the recent advances in graphic techniques and to evaluate available software packages for simulating the motion of robots. The equipment associated with the software packages is also discussed.

Interactive computer graphics for assisting human programmers

A theory exists that a graphic ‘transfer function’ of humans may be characterizable. A computer graphic terminal trained with an understanding of this function may be capable of identifying with a human and appreciably raising the potential quality of human/computer graphic dialog. An Interactive Computer Graphic Assisted Programming (ICGAP) system is described which uses computer graphics to aid in the construction of computer graphic programs, conveniencing interactive computer graphic experiments.The rich, relatively untapped fields of art and psychology deserve computer graphic science's attention. An example of one area is the psychologist's model of the process of representationalism.     

Methodologies for the cost-benefit analysis of computer graphics systems

This paper assesses the state of the art in cost-benefit analyses of computer graphics systems and suggests an approach for developing improved methodology. Cost-benefit analyses are distinguished from analyses of system performance in that the latter is directed at optimizing system performance at a given level of investment, while the former is directed at justifying the investment itself.Computer graphic system design alternatives are first outlined. Then methods of analyzing the performance and costs of computer systems in general and graphic systems in particular are discussed. With this information it is shown how cost-effectiveness analyses may be performed. The next crucial step is to conduct benefit analysis, an ill-defined art. The results of benefit analysis must be combined with cost-effectiveness analysis in order to perform the desired cost-benefit analysis.An experimental methodology is suggested for better performing benefit analyses of computer graphics systems. A more rigorous formulation of the cost-benefit procedure is then outlined. No attempt is made in this report to actually perform such an analysis.     

Knowledge visualization: A new framework for interactive graphic interface design

Diagrams communicate massive amounts of information at a glance. Complex domains can be simplified and extended with diagrammatic notations. Computational systems can certainly benefit from the use of diagrams. However, graphic interfaces are difficult and time consuming to write. We need a way of shortening the graphic-interface building cycle so that it is relatively easy and fast to add a graphic interface to any application that may benefit from it.A general-purpose, graphic-interface-building tool kit that a designer or user, not a programmer, can use to design and attach graphic interfaces to applications can greatly speed up and lower the costs of adding graphics to systems. In this paper, I describe a new framework for interactive graphic interface design. The framework will enable graphic-interface-building tools which are general purpose, inter-active, and application-specific.The framework consists of a taxonomy (ontology) of visual properties that span sub-object properties, full objects, and the relationships between objects. The taxonomy forms a skeleton on which to hang methods for manipulating these visual properties, objects, relations, and composites. The methods consist of the generation of prototypes, the recognition of properties in objects, and mouse manipulation functions for modifying properties in an object. Further characteristics of the framework are that the properties are composable, that objects can be explicitly, incrementally described through repeated composition and application of recognition methods, and that the composition of properties to form more fully described and more complex objects is recursive. This makes the framework and the objects within it quite flexible, incremental, uniform, and modular.     

视觉游戏与设计创意

"视觉游戏"并非是艾尔·塞克尔所研究的视觉科学中的幻觉现象,而是一种设计理念。这种理念不仅体现在设计师追求设计乐趣、享受设计过程的态度上,而且体现在设计师对于挑战"规则"、突破"传统"、寻求自由轻松的设计氛围的追求中。现代平面设计具有较强的视觉游戏特征,主要体现在趣味性、游戏性、无序性、偶然性这四个方面。当平面设计以"视觉游戏"的形式展现时,它在图形、文字和编排的创意与表现上都呈现出新的面貌。
