dc.description.abstract-translatedLamps are difficult to market via websites. Renderings and photographs of showrooms rarely fit consumer pref erences and demands and the technical specifications for lighting are unintuitive and difficult to understand for non-experts. This poses a challenge for lighting system manufacturers and suppliers, as customers increasingly make purchases online. Giving customers the option to see how a lamp affects the environment would provide them with an intuitive way to find a suitable product. Unfortunately, expensive global illumination rendering methods are required to accurately simulate the effect of a specific lamp on the environment. However, contemporary meth ods are not suited for low-end consumer hardware or interactive web-applications. Therefore, we present a new texture-based global illumination method that simulates the effect of specific lamps on complex, polygonal 3D geometries on the GPU. Our method employs iterative light propagation to pre-compute the illumination in texture space, leveraging GPU-based bounding volume hierarchies. Our method can provide pre-calculated physics-based lighting on demand in under a second for interactive scenarios in browsers using WebGl - outperforming state-of the-art offline renderers significantly.en
