A system and method for remote rendering of computer graphics wherein user transactions are reliable and the transmission of rendered graphics is relatively fast. The invention is implemented in a client server context, where a computer graphics application and rendering resources are located at a server. A user controls the graphics application through a client machine connected to the server through a computer network. The user's commands are sent from the client to the server, while rendered computer graphics are transmitted from the server to a display at the client. Different transport protocols are used, depending on the requirements of a particular transmission. Data related to user interactions is transmitted using a relatively reliable transport protocol, such as TCP. Rendered subject graphics data is transmitted from the server to the client using a less reliable but faster transport protocol, such UDP.

Applying different transport mechanisms for user interface and image portions of a remotely rendered image

A floating point rasterization and frame buffer in a computer system graphics program. The rasterization, fog, lighting, texturing, blending, and antialiasing processes operate on floating point values. In one embodiment, a 16-bit floating point format consisting of one sign bit, ten mantissa bits, and five exponent bits (s10e5), is used to optimize the range and precision afforded by the 16 available bits of information. In other embodiments, the floating point format can be defined in the manner preferred in order to achieve a desired range and precision of the data stored in the frame buffer. The final floating point values corresponding to pixel attributes are stored in a frame buffer and eventually read and drawn for display. The graphics program can operate directly on the data in the frame buffer without losing any of the desired range and precision of the data.

Floating point computer system with fog

A system and method for providing Personal Cloud computing and for hosting applications and/or content may employ a network attached storage device on which virtual machine monitors (T-cups) and logical devices (Ts) are instantiated in memory. Each T may include hosted content, application modules, a server module configured to host the modules and/or content, and an interface module configured to provide access to the modules and/or content in response to detecting an authorized key. Detecting an authorized key may include communicating with a name server to determine if a T instantiated on a storage device coupled to the system is associated with a device identifier on a list of device identifiers authorized to access the module(s). The storage device may be a computer, camera, frame, phone, audio/video player, or portable storage device. The name server may be configured to authenticate Ts, define T ownership, and/or establish friend-to-friend networks between Ts.

One aspect of the invention is a method for data retrieval. The method includes the step of rendering geometry from a selected perspective () to produce a plurality of data values (, T'). The method also includes the steps of storing at least a subset of the plurality of data values (, T&#x2032;) in a memory () and computing a plurality of texture coordinates (a&#x2032;&#x2013;d&#x2032;) of the geometry from a projective transformation corresponding to the selected perspective (). The method also includes the step of retrieving at least one of the stored data values (T) that correspond to the texture coordinates (a&#x2032;&#x2013;d&#x2032;) from the memory ().

Data retrieval method and system

A system and method for generating a image, where the image comprises both a graphical user interface (GUI) and a subject graphics image. A first graphics pipeline renders the subject graphics image. A second graphics pipeline renders the GUI graphics data. A compositor then composites together the rendered subject graphics data that is produced by the first graphics pipeline, and the rendered GUI graphics data that is produced by the second graphics pipeline.

System and method for decoupling the user interface and application window in a graphics application

A method and system are provided for executing SIMD instructions using graphics technology. A SIMD instruction is received and interpreted. The specific data needed for the SIMD instruction is identified. Texel addresses where the specific data are stored are recalled and frame buffer pixels to be used to support the SIMD instruction are selected. In an alternative embodiment, these texel addresses are stored in frame buffer pixel channels such that the pixel containing a particular address will be the pixel to hold the data stored at that address for the SIMD operation.
