Rayfront

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.

This software is designed for the daily needs of the practical lighting designer. Rayfront is equally well applied to electrical lighting and daylighting. It has no limits for geometry size and complexity, but gives you fast and accurate results for small projects as well.
