Design and implementation of a fast integral image rendering method

The computer-generated integral imaging system is a way of showing stereoscopic displays that allows users to see 3D images without wearing any special glasses. In the integral imaging system, the 3D object information is stored as elemental images, which are generated by the image mapping method. This paper reviews the previous image mapping methods, such as PRR (Point Retracing Rendering), MVR (Multi-Viewpoint Rendering), and PGR (Parallel Group Rendering). Then, it explains a new image mapping method called VVR, which shows better performance while generating similar pictures as in MVR. Finally it mentions process of making the integral imaging system, and analyzes performance. Then, it discusses some research directions for the future improvement.
