Hardware/software interaction in graphical display systems

A review of the principles and applications of display systems is given. A state-of-the-art survey is made of the various types of display devices and their disadvantages. A study is made of the problems associated with two particular display devices and solutions found by the use of hardware and software techniques. A communications line is occupied for an excessive amount of time when drawing graphs on a standard incremental plotter from a remote computer. This time was significantly reduced for low cost by using a satellite computer and trying various alternative coding techniques.A low cost interactive raster scan graphics system was developed that used a magnetic disc to refresh television monitors. This system was used to determine the best method for overcoming the crossing vector erasure problem. A system using the improvements to both the display devices is proposed as a further development.<p

Second Annual AEC Scientific Computer Information Exhange Meeting. Proceedings of the Technical Program Theme: Computer Graphics

The topic of computer graphics serves well to illustrate that AEC affiliated scientific computing installations are well represented in the forefront of computing science activities. The participant response to the technical program was overwhelming--both in number of contributions and quality of the work described. Session I, entitled Advanced Systems, contains presentations describing systems that contain features not generally found in graphics facilities. These features can be roughly classified as extensions of standard two-dimensional monochromatic imaging to higher dimensions including color and time as well as multidimensional metrics. Session II presents seven diverse applications ranging from high energy physics to medicine. Session III describes a number of important developments in establishing facilities, techniques and enhancements in the computer graphics area. Although an attempt was made to schedule as many of these worthwhile presentations as possible, it appeared impossible to do so given the scheduling constraints of the meeting. A number of prospective presenters 'came to the rescue' by graciously withdrawing from the sessions. Some of their abstracts have been included in the Proceedings
