Abstract

We have developed an simplified image-based rendering technique which exploits real image texture mapped boards. Our aim is to improve the reality of visual contents and the efficiency of visual contents development phase in order to construct cyber spaces. The shape of the texture and the arrangement of the board are altered so as to follow the user's changing point of view(POV) and look as if actual objects exist. We call this board "Texture-Object". The transformation process according to user's POV is as follows: One real image texture is divided into some subsections to each of which we apply a different Affine transformation. In this paper we will present its design concept, display process, implementation of our prototype system, evaluation for making contents of virtual cities.
