Reduced Dual-Formulation for Analytical Anisotropic Single ScatteringVincent Pegoraro, Mathias Schott, Steven G. Parker[paper] [poster] [bibtex] Abstract: An analytical approach to solving anisotropic single scattering from point light sources in homogeneous media was recently derived via a dual-formulation of the air-light integral. In this paper, we demonstrate how to reduce the evaluation of the terms involved in the solution and provide an efficient and practical implementation substantially increasing the real-time performance characteristics.
