Spectral rendering The core of Luxrender is fully spectral. Unlike traditional rendering software, which only operates on distinct colors (such as red, green and blue), Luxrender uses individual wavelengths. This allows LuxRender to correctly deal with wavelength dependent effects, such as dispersion, or accurately capture the color of incandescent lights. It also makes the rendered images look more natural.
These images are hemispherical panoramas, taken as addition to my Virtualvienna Project. You can find there some of the panoramas as full panorama in a bigger size than here.
This software was developed (or is under development) within the higher education and research community. It’s stability can vary (see fields below) and its working state is not guaranteed.
