PIX - AN OBJECT-ORIENTED NETWORK GRAPHICS ENVIRONMENT

This paper describes PIX, a system to enhance X with PHIGS' three dime nsional graphics capability. Our goal is to provide the user with the conveniences and features of PHIGS-which is an international standard for 3D computer graphics programming-in a network-oriented, hardware-i ndependent environment. To ensure portability of our system, we have d esigned and implemented PIX under the X Window System, a network-trans parent windowing system developed at MIT. Some of PIX's important and unique features are: an object-oriented data structure design, a netwo rk-oriented system architecture, separable server processes to take ad vantage of a dedicated 3D graphics hardware. In particular, simulation s with the 3DP, a three Dimensional Processor developed at Computer Mo tion Inc., have indicated promising potential for PIX to evolve into a high performance graphics system.
