Glassless 3D display requires multiple images taken from different viewpoints to show a scene. Thus, generating such a large number of viewpoint images effectively is emerging as a key technique in 3D video technology. Image-based view synthesis is a technique of generating required virtual viewpoint images using a limited number of views and depth maps. In this paper, we propose an algorithm to compute virtual views much faster by using multi-texture image structure of graphics processing unit(GPU). We demonstrate the effectiveness of our algorithm for fast view synthesis through a variety of experiments with real data.
