Real-time per-pixel viewpoint interpolation

Real-time rendering of complex scenes is a crucial problem in computer graphics. In this paper we present a simple and efficient real-time (high frame rate) rendering method in which the computational cost is almost independent of the scene geometric complexity. The main advantages of our method compared to other height field warping approaches such as relief texture mapping, is that the scene has no restriction concerning the nature of its geometry. This method can be considered as an hybrid geometry and image-based representation of the scene, viewed along a 3D camera path. The final image in an arbitrary viewpoint on this path is rendered using a very small number of images corresponding to the reference viewpoints. Real-time rendering is performed using the pixels shaders functionality of current graphics hardware
