Brotens has released Room Lighting Calc for Mac OS X. It can generate morphologically defined parametric objects (vaults, quadric, domes, etc..) or generate primitives (cubes, spheres, cones, etc.).

The light sources, calculated as volumetric sources, are managed entirely by Room Lighting Calc, which allows you to import, display, edit and format IESNA LM-63, EULUMDAT, and DXF formats. Photometric solids are summarized in 36 azimuthal C-curves and 180 zenithal gamma-angles, while the color of the lamps is given by the color temperature or real color. Room Lighting Calc can export to RTF a complete list, formatted according to user needs, of the installed products and special items, full of economic computing and electrical power.

Room Lighting Calc works both in metric or imperial units, runs on Apple computers running OS X 10.8 or higher and uses OpenGL for rendering. It’s available at both the Mac App Store and the Broton web site ( It’s priced at US$48.99 for a limited time.
