Abstract : Graphics packages that have been implemented based on the 1979 ACM/SIGGRAPH Core Standard Proposal were investigated. Two packages were identified that best met AFIT's needs, based on host processor implementation and availability. These two packages were GRAFCORE, from the Lawrence Livermore National Laboratory, and GWCORE, from The George Washington University. GRAFCORE was the package initially selected for installation on the AFIT VAX. GWCORE was also obtained, but not installed. Both packages currently provide output-only capability. Problems with GRAFCORE installation that had to be overcome included characters lost in transmission, incomplete files, and the need to manually convert some of the code from the LRLTRAN language used at Lawrence Livermore into standard FORTRAN. Future efforts in this area should begin with device driver design and implementation for both graphics packages, followed by implementation of graphics-input routines. (Author)
