This paper introduces the concept of ray-based representation of spatial data and proposes a new method for creating the photo-realistic virtual world. In this method, the whole ray data of the world are treated as a set of orthogonal views of scene objects. The advantage of this approach is to allow the synthesis of any perspective view by gathering appropriate ray data from the set of orthogonal views independently of any geometric representation. First, several perspective views of the real world are taken as a set of real ray data. Secondly, orthogonal views of the world are synthesized from the captured real ray data. Then, structural models corresponding to each perspective view are locally estimated and adaptively stitched each other in order to interpolate the cracks on the orthogonal views. This approach can avoid the difficulty in estimating a unique structural model of the world.
