Computer-aided design of large-scale integrated circuits - A concept

Circuit design and mask development sequence are improved by using general purpose computer with interactive graphics capability establishing efficient two way communications link between design engineer and system. Interactive graphics capability places design engineer in direct control of circuit development

Computer graphics application in the engineering design integration system

The computer graphics aspect of the Engineering Design Integration (EDIN) system and its application to design problems were discussed. Three basic types of computer graphics may be used with the EDIN system for the evaluation of aerospace vehicles preliminary designs: offline graphics systems using vellum-inking or photographic processes, online graphics systems characterized by direct coupled low cost storage tube terminals with limited interactive capabilities, and a minicomputer based refresh terminal offering highly interactive capabilities. The offline line systems are characterized by high quality (resolution better than 0.254 mm) and slow turnaround (one to four days). The online systems are characterized by low cost, instant visualization of the computer results, slow line speed (300 BAUD), poor hard copy, and the early limitations on vector graphic input capabilities. The recent acquisition of the Adage 330 Graphic Display system has greatly enhanced the potential for interactive computer aided design

An application of interactive computer graphics technology to the design of dispersal mechanisms

Interactive computer graphics technology is combined with a general purpose mechanisms computer code to study the operational behavior of three guided bomb dispersal mechanism designs. These studies illustrate the use of computer graphics techniques to discover operational anomalies, to assess the effectiveness of design improvements, to reduce the time and cost of the modeling effort, and to provide the mechanism designer with a visual understanding of the physical operation of such systems

Interactive Computer Graphics Applied to Continuous Systems Simulation

Interactive computer graphics is beginning to achieve wide acceptance as a valuable tool in assisting the everyday engineer in his engineering activities. This paper describes one of the uses of interactive computer graphics in assisting the engineer - the modeling of continuous systems using CSMP. Continuous systems modeling using interactive computer graphics is being used extensively at The Boeing Company, Huntsville, Alabama. As a result of this utilization many additional requirements have been placed on CSMP. These requirements will be presented in this paper

Drill user's manual

Interactive Computer Graphics - An Advanced Computer Technology

Computers have been an invaluable aid as man has grappled with advancing technology. As the computer tool has become more sophisticated, man\u27s ability to master new technologies and applications has been proportionately accelerated. One of the very promising sophistications today is graphics. A research project to: 1. Determine capability and 2. Promote utilization has been underway at Boeing Huntsville and is the subject of this paper. Reference 1 is devoted to some of the mechanics of the program and its operation. This complimentary paper will document the graphics program as an entity, its relationship to the parent organization\u27s function, and some of the details of selected applications

Multi-agent evolutionary systems for the generation of complex virtual worlds

Modern films, games and virtual reality applications are dependent on convincing computer graphics. Highly complex models are a requirement for the successful delivery of many scenes and environments. While workflows such as rendering, compositing and animation have been streamlined to accommodate increasing demands, modelling complex models is still a laborious task. This paper introduces the computational benefits of an Interactive Genetic Algorithm (IGA) to computer graphics modelling while compensating the effects of user fatigue, a common issue with Interactive Evolutionary Computation. An intelligent agent is used in conjunction with an IGA that offers the potential to reduce the effects of user fatigue by learning from the choices made by the human designer and directing the search accordingly. This workflow accelerates the layout and distribution of basic elements to form complex models. It captures the designer's intent through interaction, and encourages playful discovery
