We present a novel technique for capturing spatially and temporally resolved light probe sequences, and using them for rendering. For this purpose we have designed and built a Real Time Light Probe; a catadioptric imaging system that can capture the full dynamic range of the lighting incident at each point in space at video frame rates, while being moved through a scene. The Real Time Light Probe uses a digital imaging system which we have programmed to capture high quality, photometrically accurate color images with a dynamic range of 10,000,000:1 at 25 frames per second.By tracking the position and orientation of the light probe, it is possible to transform each light probe into a common frame of reference in world coordinates, and map each point in space along the path of motion to a particular frame in the light probe sequence. We demonstrate our technique by rendering synthetic objects illuminated by complex real world lighting, using both traditional image based lighting methods with temporally varying light probe illumination and an extension to handle spatially varying lighting conditions across large objects.
