abstract = {Industrial applications like luminaire development (the  creation of a luminaire in terms of geometry and material)  or lighting design (the efficient and aesthetic placement  of luminaires in a virtual scene) rely heavily on high  realism and physically correct simulations. Using typical  approaches like CAD modeling and offline rendering, this  requirement induces long processing times and therefore  inflexible workflows. In this paper, we combine a GPU-based  progressive photon-tracing algorithm to accurately simulate  the light distribution of a luminaire with a novel  multi-resolution image-filtering approach that produces  visually meaningful intermediate results of the simulation  process. By using this method in a 3D modeling environment,  luminaire development is turned into an interactive process,  allowing for real-time modifications and immediate feedback  on the light distribution. Since the simulation results  converge to a physically plausible solution that can be  imported as a representation of a luminaire into a  light-planning software, our work contributes to combining  the two former decoupled workflows of luminaire development  and lighting design, reducing the overall production time  and cost for luminaire manufacturers.},
