Radiance project is a set of tools which provide an advanced lighting simulation software package.

It allows very detailed definition of materials' and light sources' properties through the use of advanced techniques like brdf and ies files, as well as a powerful mathematical scripting language, resulting in accurate renderings of scenes which are usually imported from CAD and 3D modelers.

It uses the hybrid approach of Monte Carlo and deterministic ray tracing to achieve a reasonably accurate result in a reasonable time.

What's New in This Release:

Memory requirements for octree were reduced by a factor of 8.
Byte-swapping input and output was added to rcalc along with extra error checking for source surfaces, a -spec option in falsecolor to restore the original spectral color scale, the ability to incorporate BSDF data in calculations, and support for persistent rendering and for cumulative calculations.
Ray weights were corrected for material mixtures.
Bugs in the shadow cache were fixed.
Pixel alignment was fixed in pcomb for size reduction and enlargement.
