Radiance 4.2

Highly accurate ray-tracing software system for UNIX computers
Radiance is a highly accurate ray-tracing software system for UNIX computers that is licensed at no cost to users for non-commercial use; commercial use licenses including distribution rights are available for a fee.

Radiance is a suite of programs for the analysis and visualization of lighting in design.

Input files specify the scene geometry, materials, luminaires,time, date and sky conditions (for daylight calculations). Calculated values include spectral radiance (ie. luminance color), glare indices and irradiance (illuminance color). Simulation results may be displayed as color images, numerical values and contour plots.

The primary advantage of Radiance over simpler lighting calculation and rendering tools is that there are no limitations on the geometry or the materials that may be simulated. Radiance is used by architects and engineers to predict illumination, visual quality and appearance of innovative design spaces, and by researchers to evaluate new lighting and daylighting technologies.

NOTE: Radiance is licensed and provided under the terms of the Radiance OpenSource License Agreement. Radiance is free for non-commercial use.

What's New in version 4.1
  • Changed ranimate behavior so remote login under a different user doesn't necessarily require the presence of the originating user's home directory.
  • Changed standard transmission function normalization back to what it was in version 3.5, following recommendation of David Geisler-Moroder, who pointed out that the revised BTDF increased too much at grazing.
  • Changed rad behavior with -N >1 on single view to call rpiece.
  • Updated SCons build system for MINGW compilation, thanks to Christian Kohler.
