While working for the Laboratory for Atmospheric and Space Physics I took over as the primary developer for a satellite visualization tool called LASPview. Intended to function as an always-on kiosk for visitors, LASPview aggregates data from a multiple sources and presents a near real-time representation of the solar system and multiple NASA satellite missions.
Despite being a fairly modest tool, as a result of my efforts LASPview leverages OpenGL Core Profile to achieve true solar-system scale rendering using a logarithmic depth buffer, astronomically correct positioning and illumination of planetary bodies, and physically-based lighting using the Cook-Torrence, Oren-Nayar, and Lommel lighting models.
