The authors present in their paper the possibilities of the application of computer graphics and compute animation for visualisation of the electric heart field (EHF). They describe the construction of three-dimensional potential maps by the methods of interpolation, perspective projection, hidden line elimination and text generation. They also present a method for making of animation films showing the electric activity of the heart by using 80 three-dimensional potential maps recorded at different intervals over the entire cardiac cycle.

The computer Graphic Center (ZGDV) has realized a training and education program in cooperation with partners from Spain, Portugal, United Kingdom and Federal Republic of Germany in different application areas based on techniques of computer graphics. After the successful introduction of computers even in small companies and education institutions, there is still a lack on the use of this technology which hinders greater productivity: adequate education and training resources using the appropriate methods and strategies are missing. This is valid for academic areas as well as for industrial areas. In the future this task must be covered by public, private and industrial institutions. The COMETT project is a milestone in this direction. The main task is aimed at supporting the teacher and the student with hardware and software tools for a CAD training environment.

Traditionally, computer graphics courses have centered on desktop environments using well-known frameworks such as OpenGL. That approach might become obsolete in a new context in which developers must create applications for smart phones, tablets, and rich Internet applications. Teaching computer graphics in this situation is becoming difficult; traditional tools don't address these new requirements in an integrated way. To deal with this situation, the Processing development environment provides high-end solutions in visualization, animation, and interaction, while letting students deploy their programs on desktop computers, smart phones, tablets, and websites. Instructors can introduce devices and interaction paradigms in just a few hours. In an introductory computer graphics course, Processing dramatically boosted students' motivation. Their work wasn't just visible in the lab; they could show it to classmates and friends on their own smart phones, tablets, and websites.

The implementation of the computer graphics Metafile (CGM) at McDonnell Douglas Corporation is described. It was implemented to answer the need for a single computer graphics metafile format as part of an integrated information interchange infrastructure that would integrate the creation and delivery of technical information in the corporation. The CGM enables the interchange of computer documents in a heterogeneous computer environment. The relationship of the CGM to the interchange of electronic compound documents is discussed.
A FORTRAN subroutine is presented which efficiently draws a bundle of lines that follow a given set of points creating the impression of a thick line of uniform width following the points.

The JPL computer graphics Laboratory (CGL) has been using advanced computer graphics for more than ten years to simulate space missions and related activities. Applications have ranged from basic computer graphics used interactively to allow engineers to study problems, to sophisticated color graphics used to simulate missions and produce realistic animations and stills for use by NASA and the scientific press. In addition, the CGL did the computer animation for “Cosmos”, a series of general science programs done for Public Television in the United States by Carl Sagan and shown world-wide. The CGL recently completed the computer animation for “The Mechanical Universe”, a series of fifty-two half-hour elementary physics lectures, led by Professor David Goodstein of the California Institute of Technology, and now being shown on Public Television in the US. For this series, the CGL produced more than seven hours of computer animation, averaging approximately eight minutes and thirty seconds of computer animation per half-hour program. Our aim at the JPL computer graphics Laboratory (CGL) is the realistic depiction of physical phenomena, that is, we deal primarily in “science education” rather than in scientific research. Of course, our attempts to render physical events realistically often require the development of new capabilities through research or technology advances, but those advances are not our primary goal.

This article reports on the advances of the computer animation in Japan. Japanese animators continue to produce thousands of hours of 2D cartoons every year. Japan's traditional pictorial language is well suited to the visual immediacy of animation. Furthermore, Japanese animation is notable for its dynamic calligraphic style. The continuing focus of Japan on 2D has not hurt the Japanese animation industry. In fact, 60 percent of all cartoons shown on television screens around the world are made in Japan.
