Image generation design for ground-based network training environment

The SIMNET program, the first large scale application of distributed simulation to tactical team training, is briefly described. Its success has fostered interest in distributed simulation technology and has provided a foundation for the requirements of the next generation of visual systems. The most challenging requirements for such systems specific to the needs of ground based tactical training environments are presented. An architectural approach to the design of an image generator (IG) satisfying these requirements is discussed. This includes a high level system diagram and the architectural concepts which provide solutions to high level occulting, localization of image complexity due to many moving models, dynamic allocation of processing resources, independent scalability of polygon and pixel processing, the need for standard interfaces, and simulation of special environmental effects such as tactical smoke. Architectural efficiencies and performance levels obtained with these methods are quantified.<
