....with an underlying surface representation can be efficiently implemented as a projective texture map [Hec91] and is widely supported in rendering engines, real time displays, and graphics hardware. Image based modeling and rendering techniques that do not exploit a geometric representation [Mat02, Che93, Lav94] use morphing maps of adjacent images to render a new images from viewpoints not contained in the original set of basis views. Interpolation requires accurate camera calibration to the object coordinate system, or known relative calibration between the exemplar views for constrained epipolar ....

....of separation we have in mind is most closely related to video matting techniques, several of which are widely used. The blue screen method and multi background matting rely on backgrounds with special mathematical properties and require a tightly controlled studio environment to be successful [8]. Our approach falls into a second category which uses clean plates, images of the static background of the scene. Clearly, 3D reconstruction as well as background separation could benefit greatly from a known solution to the respective other problem: If the static background pixels in an image ....

....the frame rate drops down as the pass number increases. Fortunately, the next generation graphics hardware, e.g. the Radeon 9700 from ATI or the GeForce FX from nVIDIA, will support eight pixel pipelines. This means eight input images can be processed in one single pass. A plot in the work [13] shows that by using eight silhouettes, the rendering quality of visual hulls improves considerably. Therefore, the new graphics hardware should be capable of providing convincing visual hull rendering results in real time. 6 Conclusions and Future Work In this paper we have presented a new ....

....rendering, some topics from point based modeling are covered as well. This includes: visibility, image reconstruction, data structures for point samples, levelof detail control, compression, object sampling. Very related problems that we don t discuss here are acquisition of real world objects [24, 36, 37], conversion of point based surfaces to other representations (often denoted as surface reconstruction [28, 5, 11, 52] see [3] for an overview) volume rendering [68, 66] and image based rendering [64] 1.2 Report Organization The report consists of three main parts. The first part is ....
....solved. Possible direction would be to to design a projection similar to that in MLS surfaces, but in a way that would intrinsically contain the ray intersection. 3. 7 Object Sampling Sample sets of object surfaces can be obtained either by scanning a real object with a 3D scanning device [24, 36, 37] or by sampling a synthetic object with a sampling algorithm. Here we discuss different sampling algorithms for synthetic objects. 3.7.1 Classification We classify the sampling techniques according to the following criteria: randomized deterministic, in preprocess on the fly (i.e. during ....
