Abstract

We present a novel technique to minimize the number of light sources in a virtual 3D scene without introducing any perceptible changes to it. The theoretical part of the thesis gives an overview on previous research in the field of automated lighting design, followed by an introduction to the theory of rendering and genetic algorithms. The implementation is done as extension called "Light Source Cleaner" to LuxRender, a physically based, open-source renderer. The algorithm adjusts the intensities of the light sources in a way that certain light sources can be canceled out, thus enabling to render a similar image with significantly less number of light sources, introducing a remarkable reduction to the execution time of scenes where many light sources are used.
