This paper describes a new approach for building a photo-realistic large-scale virtual world. For this purpose, an image-based rendering (IBR) technique seems promising compared to conventional CG techniques. We developed a new image interpolation method which can generate novel images with little distortion. By dividing base image into layered images and applying image interpolation procedure layer by layer, we can avoid the problem of occlusion. This method makes it possible for a user to freely walk around positions where base images are sampled. In order to record existing large-scale scenes with the information of the position and the orientation, we developed a novel image capturing system. In this paper, some experimental results are shown as well as the details of the approach and the system.
