Best Lighting Design Software for Windows

Rayfront is a platform-independent toolkit that provides a graphical user interface to the lighting simulation software Radiance. It can be operated as an extension to Autocad or Intellicad, together with the 3Dsolar building modeller, or as a standalone program. Radiance is the industry standard raytracing engine for physically correct lighting simulations (see comparisons). While Radiance can be downloaded for free from LBNL, only a toolbox such as Rayfront enables people like you and me to use it effectively on desktop computers and in your local network. You can also use Rayfront together with many other CAD and modelling programs, as it reads all DXF files, and translators for a large number of other data formats are included. Just select the free or commercial geometry modeler of your preference, and there will be a way to use it's output data with Rayfront.
