摘要: The view frustum culling technique described herein allows Free Viewpoint Video (FVV) or other 3D spatial video rendering at a client by sending only the 3D geometry and texture (e.g., RGB) data necessary for a specific viewpoint or view frustum from a server to the rendering client. The synthetic viewpoint is then rendered by the client by using the received geometry and texture data for the specific viewpoint or view frustum. In some embodiments of the view frustum culling technique, the client has both some texture data and 3D geometric data stored locally if there is sufficient local processing power. Additionally, in some embodiments, additional spatial and temporal data can be sent to the client to support changes in the view frustum by providing additional geometry and texture data that will likely be immediately used if the viewpoint is changed either spatially or temporally.

摘要: An object placed on an interactive display surface is detected and its position and orientation are determined in response to IR light that is reflected from an encoded marking on the object. Upon detecting the object on an interactive display surface, a software program produces a virtual entity or image visible through the object to perform a predefined function. For example, the object may appear to magnify text visible through the object, or to translate a word or phrase from one language to another, so that the translated word or phrase is visible through the object. When the object is moved, the virtual entity or image that is visible through the object may move with it, or can control the function being performed. A plurality of such objects can each display a portion of an image, and when correctly positioned, together will display the entire image, like a jigsaw puzzle.
