摘要： Methods and systems for utilizing a parallel conversational thread during a remote collaboration are described. In one embodiment, a managing entity is utilized to establish a first communications path for a remote collaboration of at least two parties. Then, a request for a parallel conversation is received from at least one of the at least two parties during the remote collaboration. The managing entity then establishes a second communications path for the parallel conversation between the at least two parties. Wherein, the enabling of the parallel conversation on the second communications path is performed without inhibiting the first communications path, such that a portion of a first party can have a parallel conversation with a portion of a second party on the second communications path while the first communications path for the remote collaboration remains active.

摘要： A method of communicating gaze. Specifically, one embodiment of the present invention discloses a method of communicating gaze in an immersive virtual environment. The method begins by representing an immersive virtual environment on a monitor that is viewable by a viewing participant. The monitor displays a plurality of objects in the virtual environment. The physical gaze of the viewing participant is tracked to determine a physical direction of the physical gaze within a physical environment including the viewing participant. Thereafter, a viewed object is determined at which the viewing participant is gazing. Then, a virtual direction is determined between the viewing participant and the viewed object in the immersive virtual environment. A model of the viewing participant is rotated based on the physical and virtual directions to render a view of the viewing participant such that the viewing participant is facing the viewed object in the immersive virtual environment.

摘要： Methods and apparatus are provided for volumemetric scene reconstruction. Given a set of images of the scene taken from arbitrary but known locations, a 3D model of the scene is reconstructed. Voxels are used to model the scene and exploit the fact that surface points in the scene, and the voxels that represent them, project to consistent colors in the input images. Input cameras may be placed at arbitrary locations in and around the scene. When checking the color consistency of a voxel, the entire set of images from which the voxel is visible is used. A GVC algorithm utilizes item buffers which contain, for each pixel in each image, the ID of the closest voxel that projects onto to the pixel. A GVC-LDI algorithm uses layered depth images which store at each pixel location a list of all the surface voxels that project onto the pixel, sorted according to the distance of the voxel from the image's camera.

摘要： A method for real-time video communication. Specifically, one embodiment of the present invention discloses a method of video conferencing that captures a plurality of real-time video streams of a local participant from a plurality of sample viewpoints. From the plurality of video streams, a new view synthesis technique can be applied to generate a video image stream in real-time of the local participant rendered from a second location of a second participant with respect to a first location of the local participant in a coordinate space of a virtual environment. A change in either of the locations leads to the modifying of the video image stream, thereby enabling real-time video communication from the local participant to the second participant.

摘要： A method of generating a three-dimensional model of a scene from a plurality of photographs of the scene. The method includes voxels in an interior region and an exterior region of the scene in question and then examines the voxels to determine if they are empty or part of the objects in the scene. The interior region is divided into a plurality of interior voxels, that are preferably of the same size. The exterior region surrounds the interior space and is divided into exterior voxels having different sizes. The size of the exterior voxels increases as a function of the distance between the voxel and the interior region. The voxels that are furthest from the interior region are preferably infinite in size.

摘要： A graphics system that employs parametric texture maps. The graphics system renders surface features of a 3D object in a manner that is direction dependent but without the time consuming and expensive calculations involved in the evaluation of lighting equations on a per pixel basis. A parametric texture map holds a set of parameters that define a surface structure in a manner in which the appearance of the surface structure varies in response to a direction vector. The direction vector may be any user-defined vector including a light source vector or a half-angle vector. The parameters are those of a predetermined equation, the evaluation of which does not involve vector calculations. The equation may take any form including a polynomial equation or a non-polynomial equation. The graphic system renders a polygon with the surface structure using the equation.
