Patent US 8,553,028

Methods, apparatuses and systems directed to efficiently circumventing the limitations of client side rendering of virtual worlds. In a particular implementation, a proposed system renders each client viewport remotely, removing the burden of rendering a 3D scene from the local client device. 3D viewports, rather than being rasterized on the local client, are instead generated on a remote render device which then transmits a visual representation of the viewport to the client device in a format (including, but not limited to a video stream) which the client can use to display the scene without requiring complex 3D rasterization. This process eliminates the need for the client to have any specialized 3D rendering software or hardware, or to install or download any persistent render assets on the local system. The hardware requirements for the client are therefore roughly equivalent to those needed to play a continuous video stream.
