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.
