It creates simulations by accurately tracing up to several million light rays through mathematical models of ice crystals.
- Simulations can be run immediately. Select from ready to run simulations of common and rare halos with text descriptions.
- Crystals. Halos from all crystals are simulated; hexagonal plates, columns, pyramidals and non water-ice crystals which might be found in other planetary atmospheres.
- Orientations. Files for plate, singly oriented columns, Parry and Lowitz orientations included. Others can be generated. Axial dispersions and dispersion distributions can be specified.
- Complex halo displays are simulated. HaloSim simultaneously computes up to twelve crystal-orientation combinations.
