Abstract:

A large number of the SurvivabilityLethality Analysis Directorate s SLAD s software tools need to display geometric data. This project explored options for improving the speed and clarity with which SLAD s tools can display geometry. The goal was to reduce the amount of human effort and elapsed time necessary to prepare complex models for use in analysis and visualization tasks. We investigated several avenues for high-speed visualization and worked to update BRL-CAD s graphics display system to support more modern display layers. While additional work remains, we identified high-performance techniques and achieved the first stages of display system improvements.
