Raster scanned graphics terminals provide several features not found in standard line drawing displays. Among them are area fill and an extensive color palette. Hardware support for such functions is becoming cost effective and available in a variety of forms. What is now needed is high level, device independent software that assists in the generation of and interaction with these terminals. To accomplish this, a project has been undertaken jointly by Sandia Laboratories, Purdue University, and MEGATEK Corporation to integrate solid image capabilities into the Graphics Compatibility System, GCS. GCS is a widely used, general purpose calligraphic graphics package. Due to the similarity of the GCS model to that of the GSPC Core System, GCS provides a timely test bed for solid image extensions to a line drawing package. This paper will summarize the capabilities being implemented, the method and motivation behind each function, and suggestions for further work.
