Such particles can be large raindrops or hexagonal ice crystals.  Such codes are one of many approaches to calculations of light scattering by particles.Table of ContentsGeometric optics (ray tracing)[edit]Classification[edit]Codes for light scattering by hexagonal ice crystals[edit]Relevant scattering codes[edit]External links[edit]See also[edit]References[edit]Geometric optics (ray tracing)[edit]Ray tracing techniques can be applied to study light scattering by spherical and non-spherical particles under the condition that the size of a particle is much larger than the wavelength of light. The light can be considered as collection of separate rays with width of rays much larger than the wavelength but smaller than a particle. Rays hitting the particle undergoes reflection, refraction and diffraction. These rays exit in various directions with different amplitudes and phases. Such ray tracing techniques are used to describe optical phenomena such as rainbow  of halo on hexagonal ice crystals for large particles.Review of several mathematical techniques is provided in series of publications.The 46\u00b0 halo was first explained as being caused by refractions through ice crystals in 1679 by the French physicist Edm\u00e9 Mariotte (1620\u20131684) in terms of light refraction [1]Jacobowitz in 1971 was the first to apply the ray-tracing technique to hexagonal ice crystal. Wendling et al. (1979) extended Jacobowitz’s work from  hexagonal ice particle with infinite length to finite length and combined Monte Carlo technique to the ray-tracing simulations.[2][3][4]Classification[edit]The compilation contains information about the electromagnetic scattering by hexagonal ice crystals, large raindrops, and relevant links and applications.Codes for light scattering by hexagonal ice crystals[edit]YearNameAuthorsReferencesLanguageShort DescriptionHalosimLes Cowley and Michael SchroederAtmospheric Optics sitegraphical user interfaceIt creates simulations by accurately tracing up to several million light rays through mathematical models of ice crystals.2010Halopoint2Jukka Ruoskanenwebpagegraphical user interfaceRay-tracing code for various ice crystals with graphical user interface2008HALOSKY [5]Stanley David Gedzelmansource codesRay-tracing codes for light scattering by hexagonal ice crystals.1996Ray tracing [6]Andreas Mackesource codesFortran 77 and Fortran99Ray-tracing codes for light scattering by polyhedral shaped ice crystals.Relevant scattering codes[edit]External links[edit]See also[edit]References[edit]^ E.
