Architectures for interactive raster graphics

For an interactive graphics system two major information streams can be recognized, information for the image synthesis process and information related to user input. In this paper, we present a logical model for the image synthesis pipeline and a logical model for input devices. Based on these abstractions we describe an interactive raster graphics system. requirements that go with interactive systems make it important to discuss implementation of this architecture on parallel systems. For this we emphasize on rasterization hardware and system configurability.
