....to the new view. However our algorithm accommodate the usage of VolumePro, from which, the per pixel depth information is unavailable. Moreover, to exploit the power of texture mapping hardware, we also want to avoid the per pixel warping before texture mapping as in relief texture mapping [19]. Instead, we texture map to the geometric models of the slabs. The portal model discussed in the previous section serves the purpose, in addition to reduce the parallel to perspective distortion. We can also use a more accurate model. For each slab, we create two depth images during the ....

....a grazing angle to the surface) it will give a flat, unnatural appearance to the rendering. In 3D warping a depth map is used to correctly rearrange the texture image into a new view[34] Three dimensional warping has further been developed into an e#cient method for texturing, relief texturing[39]. For instance, using a rectangular geometry model of a house and texturing it with a flat 2D texture would give un natural renderings for many views. However, using a texture composed of both an image and depth map, and relief texturing the same geometry recreates the correct views of the house ....

....In particular, we will describe how to make the texture correctly represent the variation over di#erent viewpoints of a potentially complex underlying geometry. Using the tools of 3D warping, relief textures provides an explicit geometric solution to adding 3D structure to a planar texture[39]. However, relief textures require a detailed a priori depth map of the texture element. This is normally not available in image based modeling if only uncalibrated camera video is used. An alternative way to represent the image motion caused by depth parallax is by modulating a spatial image ....

....the IBR is growing fast. The main idea of IBR is to use available photos of the scene to produce the desired scene view. There exist various technologies of IBR that differ in method of construction of new rendering view based on given photos. One of the methods is to use Relief Textures (RT) [1], where each image with depth is put on texture mapped polygon. The texture is warped according to view angle (pre warping step) and then textured polygon is projected to the output buffer (postwarping) This method works well if the object is well approximated by depth function (good example is ....

....a sensation of depth. The office of the future uses wall re projections of remotely captured images that heavily rely on image based modeling and rendering techniques. Other related work recently reported includes image based techniques for soft shadow rendering [2] and texture mapping with relief [76], a hardware architecture for warping and re rendering images [80] and an image based multi stream video processing system capable of re rendering new views from virtual cameras in real time [70] Finally, two surveys of image based modeling and rendering techniques have been published in the ....

....maps are alpha blended depending upon which ones are closest to the current view. The technique described here expands on this idea to provide more control over the process. Other image based rendering papers incorporate knowledge of the object to improve interpolation [16] 2] 5] The paper [11] changes the texture map of the object based on viewing direction to correct for distortion. With this technique a brick wall texture will appear 3D. None of the image based rendering papers deal directly with changes that happen when Figure 1: Meshes constructed for each layer of cells. The level ....

....motion of 3D points using optical flow. Dally et al. 5] present a method to build hierarchical object representations from points. Shade et al. 19] introduce layered depth images to obtain a complete sampling of the objects rather than just a sampling of the visible surfaces. A recent approach [14] factors the warping equation into two steps simplifying the reconstruction. Somewhat related to layered depth images of 3D geometry are volume representations. These have been rendered using splatting of individual volume elements as in [25, 10, 12] or with hardware acceleration [24] All ....
