Abstract
NPSNET-IV.7J has a limited capability to display up to 10 Dismounted Infantry (DI) icons due to the enormous number of rendered polygons and computational load required. In order to provide a more realistic training scenario for the user, NPSNET-IV.8.1 requires the capability to display at least 150 independent DI entities in real-time. Requirements were satisfied by creating low-level and medium level-of-detail autonomous and controlled DI icons and their associated motion algorithms to Support existing DI models in NPSNET- IV.8.1. Additionally, view volume culling techniques were employed to reduce polygon flow through the graphics pipeline and enhance system speed. This research enhances the capabilities of the NPSNET-IV.8.1 to be able to display 150 DI icons.The inclusion of level of detail models composed of fewer polygons than an existing high level model, together with view volume culling ensure NPSNET-IV. 8.1 can satisfy sponsor requirements of displaying 150 DI icons and still maintain a frame rate of 10-15 frames per second.
