Radiance
Radiance is a suite
of tools for performing lighting simulation.
The
Radiance suite includes over 50 tools, including software to manipulate
scene data, generators, geometry converters, rendering, image
manipulation and analysis, and integration. It uses ray tracing to
perform
all lighting calculations, accelerated by the use of an octree data
structure.
The software is widely used for lighting analysis and
can generate accurate values for radiance/luminance (W/sr.mē,cd/mē) and
irradiance/illuminance (W/m,Lux).
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.
Features include:
- Programs for modeling and translating scene geometry,
luminaire data and material properties
- Lighting simulation itself uses ray tracing techniques to
compute
radiance values (ie. the quantity of light passing through a specific
point in a specific direction), which are typically arranged to form a
photographic quality image
- Images can be analyzed, displayed and manipulated within the
package
- Conversion to other popular image file formats for export
to other packages
