A Multi-Cellular Orthographic Projection Approach to Image-Based Rendering

Abstract

Image-based rendering (IBR) techniques take the approach of rendering new images based on existing ones, effectively separating the rendering complexity from the geometric complexity of the scene they represent. With the increasing complexity of scenes currently created, these techniques have gained renewed interest. This paper presents a multi-cellular IBR approach, which uses orthographic rather than perspective projected pre-computed images. Specifically we extend our single cell orthographically projected IBR approach to a multi-cell system, and show how the pixel error can be further reduced with the use of smaller and more numerous cells.
