Real-Time Perceptually-Accurate Spectral Rendering of Atmospheric Phenomena

such as glories... rainbows... and coronas.
Glory on clouds Rainbow Corona

I have developed a highly-parallel GPGPU implementation of Mie theory which accelerates calculation of per-wavelength light scattering. Importance sampling based on solar irradiance reduces the number of wavelengths needed. Overall this work renders atmospheric glories at much faster speeds than previous serial CPU techniques. My goal is to produce perceptually-accurate images of atmospheric phenomena at real-time rates for use in games, VR, and other interactive applications.
