The system is based on a hierarchical asynchronous multiple microprocessor system. In practice this mini-computer is extendable up to 15-20 workstations. On the workstations, different graphical and non-graphical devices can be connected. The most interesting workstation is a raster graphics display device which was developed specially for the computer system described. This raster graphics display device contains a processor for the application program, two dedicated processors and two separate identical frame buffers, each of them containing one whole set of image data. Applying algorithms for anti-aliasing, virtual pixel dislocation (intensity dislocation) and multi-pixel-overlappings with hidden line (surface) elimination the image readability and quality can be increased considerably. In particular the paper deals with an anti-aliasing algorithm with a real-time hardware realization.10.1111/j.1467-8659.1985.tb00184.x33-41
