High Fidelity Obscurant Modeling for Sensor Simulations

A technique that enables new methods of obscurant modeling with faster rendering while maintaining or improving physical fidelity is proposed. The proposed technique not only exhibits the statistics of voxel based obscurants, but matches real-world data as well. The main objective from Phase II efforts will be a further refinement of the flow field and particle technique of generating physically correct and efficient obscurant model and the development of a stand-along design tool to aid in obscurant modeling. The tool will aid users in'setting up'scenes including flight-reconstructions and'what-if'scenarios. The techniques designed will also be integrated into existing scene generation software.
