Display architecture for VLSI-based graphics workstations

Abstract: At present, two popular development areas in computer graphics are improvement of interaction behaviour and more realistic graphics. The architecture for a high quality interactive workstation proposed in this work is designed such that both demanding and in a sense competing needs can be served. Calculations for generating realistic full 3-D scenes with lighting, transparency, reflection, and refraction effects, are done on the workstation itself. Intermediate results are stored to locally serve high level interaction mechanisms.

1987 Computer graphics education directory

Abstract: This is SIGGRAPH's third directory of college-level compute r graphics education, covering courses in computer graphics i n several different subjects. This directory is a single source of computer graphics course information. If you are a studen t entering college or considering a change of studies, a professiona l considering broadening your skills, or an educator seeking broade r contacts in graphics among your peers, this directory is designe d for you. We compiled the directory from the responses to a questionnair e sent out this spring, and it is completely updated since the las t edition. The responses were separated by topic according t o information received on the questionnaire and our perception o f the course's audience. The placement of some courses may not b e precise, so you may be advised to use more than one directory lis t in searching for an interesting course. For example, if you ar c interested in graphics for architects you should consult the Arts , Architecture, and Design listings, but you might also find usefu l information in the list on Engineering. CAD ; CAM, and Drafting. You should follow up interesting entries by contacting the schoo l directly for the many details of schedule, cost, and admission whic h are not included here. We should point out that our listing is no t complete since we do not know of all the computer graphic s courses being taught, and some courses which were listed in 198 5 are not here since no information was received on them. The course information we received was placed in individua l lists by the following criteria. The Concepts and Systems lis t contains courses covering general concepts in computer graphic s and systems for producing graphics ; such courses are often foun d in computer science or EECS programs and have no particula r application orientation. The Engineering, CAD!CAM, an d Drafting list contains courses which seem to be oriented towar d applications in these areas. For CAD! CAM and drafting courses , this is rather easy to tell, while the engineering orientation i s inferred from a location in an engineering program with no othe r information, or from a title such as "Engineering Compute r Graphics ." Many engineering programs, however, have courses which seem to fit the Concepts and Systems category most closel y and so are listed there. The …

One Tool among the Many

Abstract: Sunbreak Productions has been around since 1978. It is a corporate production film house. In carrying out assignments, it is not a producer of computer graphic films. Rather it uses them whenever and wherever they can make a job better or easier, and that's becoming a more and more frequent occurrence, according to Dennis Aubrey, the firm's vice president and creative director. Aubrey had a heavy background in theater before he went into film work, so he often sees things in a special, more intimate way. He has learned when the latest techniques can do a better job than the older, slower methods. Video editing

Student development of computer-graphics based instructional modules for engineering education

Abstract: I. I NTRODUCT I ON The growing power and avai labi l i ty of computers and computer-graphics hardware and software is beginning to revolutionize how mathematics, science and engineering subjects are taught and learned. Besides providing opportunities for problem quantification in ways which would be impossible without i t s number-crunching power, the computer i s also opening UP new vistas of problem visualization, presentation and interpretation.

Image Processing and Computer Graphics in the Human Sciences

Abstract: Since computers began to play an important role in everyday life, the style ofdata processing has changed greatly. At first computers were used in business and scientific applications where processing of coded and/or numerical data was the main concern. Usually, in these applications, information to be fed into a computer system is digitized and coded befbrehand, and the procedure for obtaining results from this input is almost formularized. The computer was expected to deal with vast amounts of data and to calculate very fast. Computer data processing was gradually expanded to various non-technical peripheral fields, 'not excepting the human sciences [LusiGNAN and NoRTH 1977; PATToN and HoLoiEN 1981; BAiLEy 19821. -The principal characteristic of information processing here, especially in studies like ethnology, is the significance of pattern information processing. The term pattern is used in various situations and may have a different meaning and concept in each context. Even restricted to the field of computer infbrmation processing, pattern infbrmation has by no means an exact definition, Twodimensional visual artifacts such as images and figures, are what we usually associate with patterns, but one-dimensional signals, such as sound and some specific wave fbrms, also exhibit patterns. More abstract are patterns of culture or behavior, but in this article the term pattern refers mainly to visual and one-dimensional signals. Developing a pattern-recognition system has been very difficult because the mechanisms by which human beings recognize patterns are not well known. Despite substantial basic and theoreticql research, practical results could not be obtained for a long time. In the 70s, noteworthy progress in pattern information processing was brought about by the space project. Successes in this field have spread to every engineering and scientific field, and many attempts have been made to replace or aid human infbrmation processing by computer. Research results obtained in engineering fields have supported efforts to apply these techniques to some non-technical fields, such as the human sciences and medical science, where many kinds of pattern infbrmation, e.g., photographs, sketches, maps and wave forms, have to be handled. In the medical field remarkable progress in pattern information processing has

Display of molecular models with interactive computer graphics

Abstract: Computer graphics devices offer a way to present images of three-dimensional objects with enough detail to aid human understanding of the structure of molecules. In this thesis? the Computer Aided Molecular Design system (CAMD system) will illus trate this idea. The CAMD system is an education al package designed for students in high school. The user of the CAMD system can create different molecules and store these molecules into a rela tional data base for future display. A Relational Data E-iase Management system was implicitly imple mented for the CAMD system.
