Cybercity Walker - Layered Morphing Method
Takaaki Endo · 1999
Introduction We are aiming at reconstructing a broad city area in a computer (Hirose, et al. 1999). Usually, traditional CG techniques are used to describe and present a virtual space. However, the CG techniques based on geometrical models can not draw images having photo-realistic quality in real time. Image-Based Rendering (IBR) is another promising method to describe a virtual environment. We have already developed a method to generate interpolated images without any distortion (Endo, et al. 1998) based on one IBR method called View Morphing (Seitz and Dyer 1996). This method makes it possible for an observer to freely walk around a plane, which is defined by three points where three base images are taken. However, this method has some limitations because the problem of occlusion still exists and it can not present an object having complex outline. This paper proposes a new morphing method called Layered Morphing and explains about a system called Cybercity Walker that is an
