- It has been widely recognized that lighting plays a key role in the realism and visual interest of computer graphics renderings. This hasled to research and development of image based lighting (IBL) techniques where the illumination conditions in real world scenes are captured as high dynamic range (HDR) image panoramas and used as lighting information during rendering. Traditional IBL where the lighting is captured at a single position in the scene has now become a widely used tool in most production pipelines. In this poster, we give an overview of a system pipeline where we use HDR-video cameras to extend traditional IBL techniques to capture real world lighting that may include variations in the spatial or temporal domains. We also describe how the capture systems and algorithms for processing and rendering have been incorporated into a robust systems pipeline for production of highly realisticrenderings. High dynamic range video based scene capture thus enables highly realistic renderings where traditional image based lighting, using a single light probe, fail to capture important details.
