These packages attempt to address the issues of device independence and application program portability by allowing systems to drive a wide variety of display devices as well as isolating the programmer from machine-specific graphics commands. Portability of programs is enhanced by allowing the user to move an application from one system to another. The primary programmi languages include C, Fortran, and Pascal. The quasi-standard graphical package is ACM/SIGGRAPH's Core system developed in 1977 and revised in 1979. While it was not a formally recognized standard, it did fulfill a role as a baseline specification for graphical systems [Foley et al, 1996]. The two official standards are GKS-3D, the 3-D Graphical Kernel System; and e 2000 by CRC Press LLC© 2000 by CRC Press LLC Signal Technology’s N!Power, which has object-oriented programming and linkage to X-Windows, and Bitware Research Systems’ DsqHq with real-time graphics and algorithm design.
