In this paper, we propose a new method for rendering image-based objects. An object is decomposed into a set of 1D displacement textures in a preprocessing stage. During rendering, each of these 1D displacement textures is rendered to its appropriate position in 3D space, using the hardware accelerated displacement mapping approach. Our method can represent and render complex objects with accurate appearance from arbitrary viewpoints. It can also render a complex object at a high frame rate, using commodity graphics hardware. The 1D displacement texture set is reconstructed from the images with depth maps.
