Abstract
To enhance the fidelity of numerical flow field (plume) imagery in hardware-in-the-loop (HIL) systems, new methods using particle system graphics have been developed. To render infrared (IR) images that are consistent with the underlying physical phenomenology, techniques for particle placement, pixel rasterization and drawing were developed and implemented in computer software. The software was integrated into an existing HIL scene generator and used to demonstrate several new capabilities. Moving particle systems were used to depict the internal flow and turbulence common to plumes. Persistent particle systems were used to depict the trail of hot gas and particulates left behind typical plumes. The addition of plume dynamic behaviors such as these can potentially improve HIL systems and, as a result, improve the testing of seekers and other weapon systems.
