For the seamless integration of synthetic objects within video images, generating consistent illumination is critical. This paper presents an interactive rendering system using a Graphics Process Unit-based (GPU) irradiance environment map. A camcorder with a fisheye lens captures environmental information and constructs the environment map in real-time. The pre-filtering method, which approximates the irradiance of the scene using 9 parameters, renders diffuse objects within real images. This proposed interactive common illumination system based on the GPU can generate photo-realistic images at 18 ~ 20 frames per second.
