....kind of methods in the area of image based rendering deals with spherical or cylindrical panorama pictures [Kan99] that can be looked at by viewer (e.g. Apple QuickTime VR [Che95] But these viewers are not optimized for walkthroughs in 3D scenes. So on the one hand, the well known methods [Lip80, Mil92, Che95] do not support an automatic generation of the image material or movie out of a polygon model. This means the scene has already to be given in 2D images. On the other hand, there are no prefetching policies [Zac02] that can load images in advance while the viewer pauses in order to decrease the ....

....can be achieved since the images can be directly taken from the real world. One of the most popular image based rendering software is Apple s QuickTime VR. QuickTime VR has its roots in branching movies, e.g. the movie map [8] the Digital Video Interactive (DVI) 11] and the Virtual Museum [10]. QuickTime VR [3] uses cylindrical panoramic images to compose a virtual environment, therefore provides users an immersive experience. However it only allows panoramic views at separate positions. In general, image based rendering techniques for continuous walkthrough would require a large ....

....or renovating its design. Walkthroughs of historic building (e.g. palaces or museums) can be used for educational and entertainment purposes. A museum scenario might include the ability to look at individual 3 D objects such as sculptures, and to bring up related information in a hypertext system [Miller et al. 1991]. Walkthroughs (or fly throughs) can also be done in general (e.g. outdoor) 3 D scenes. An early example of this was the Movie Maps project [Lippman, 1980] which was based on videodisc technology. Since this system was based on choosing from a number of pre stored motion sequences, the range of ....

....line inconsistency. With the stereo and automatic correction features, the SPISY can easily provide realistic 360 degree panoramic stereo views for image based VR systems. 1 Introduction Due to the capability of generating photo realistic views, image based virtual reality (VR) approach[1, 2, 3, 4, 5] has become an important mechanism for constructing the VR world. This paper deals with automatic generation of stereo panoramic views for image based VR systems. There are several commonly used method for creating panoramic images. The first one is to use panoramic cameras, e.g. Roundshot, ....

....see the intermediate views during the walking path. By using these techniques, the SPISY can easily provide realistic 360 degree panoramic stereo views for image based VR systems. 1 Introduction Due to the capability of generating photo realistic views, image based virtual reality (VR) approach[2, 3, 4, 5, 6] has become an important mechanism for constructing the VR world. In this paper, we propose a method for automatic generation of 360 degree stereo panoramas using a sequence of stereo images acquired by two cameras. Since only one of the two cameras can have its lens center passed by the vertical ....

....There are two major classes of methods for rendering 3D world for virtual reality systems. One is the geometry based approach, where the virtual world builders construct virtual worlds by building 3D models for all the objects within the virtual environment. The other is the image based approach[1, 2, 3, 4, 5, 6, 7], where the virtual world builders take some photographs at a set of viewpoints toward several directions to generate a panorama for each viewpoint. The major advantages of the image based approach include the easy construction of photo realistic virtual world, and the constant complexity of ....

....of the camera are known. The idea of using images to represent a virtual environment has been presented previously. An earlier approach uses computer controlled videodiscs to perform surrogate travel [LIPP80] A more recent approach uses digital movie technologies to construct a virtual museum [MILL92]. In both systems, a user navigates a finite set of routes and directions that have been pre determined. Our method allows greater flexibility in the navigation because the stored frames can be interpolated smoothly to synthesize arbitrary intermediate points of view. A static subject or ....

The images were rendered at 256x256 resolution using progressive radiosity [COHE88] from a model created for the Virtual Museum project[MILL92]. Figure 9 shows two intermediate images created by morphing the leftmost and rightmost images. Each image took 0.17 second to generate (excluding the preprocessing time) on a Macintosh Quadra 950. Note that for the interpolation to work properly, the source image cannot be anti aliased. ....
