Described herein are processes and devices that reduce a display quality of an area of a virtual universe to conserve computing resources. One of the devices described is a virtual resource conserver. The virtual resource conserver determines, or selects, an area in the virtual universe. A computing resource processes data for presenting the area in the virtual universe. The virtual resource conserver evaluates significance factors about the area to determine a significance of how the area is being used, or an extent to which an area is being viewed by an avatar. The virtual resource conserver reduces a display quality of the area based on the significance of how the area is being used or viewed. The virtual resource conserver thus reduces usage of the computing resource.

The present invention provides a method, system and apparatus for a time stamped visual motion sensor that provides a compact pixel size, higher speed motion detection and accuracy in velocity computation, high resolution, low power integration and reduces the data transfer and computation load of the following digital processor. The present invention provides a visual motion sensor cell that includes a photosensor, an edge detector connected to the photosensor and a time stamp component connected to the edge detector. The edge detector receives inputs from the photosensor and generates a pulse when a moving edge is detected. The time stamp component tracks a time signal and samples a time voltage when the moving edge is detected. The sampled time voltage can be stored until the sampled time voltage is read. In addition, the edge detector can be connected to one or more neighboring photosensors to improve sensitivity and robustness.

A method and an apparatus for notifying a display driver to update a display with a graphics frame including multiple graphics data rendered separately by multiple graphics processing units (GPUs) substantially concurrently are described. Graphics commands may be received to dispatch to each GPU for rendering corresponding graphics data. The display driver may be notified when each graphics data has been completely rendered respectively by the corresponding GPU.

A method and computer graphics system capable of super-sampling and performing real-time convolution are disclosed. In one embodiment, the computer graphics system may comprise a graphics processor, a sample buffer, and a sample-to-pixel calculation unit. The graphics processor may be configured to generate a plurality of samples. The sample buffer, which is coupled to the graphics processor, may be configured to store the samples. The sample-to-pixel calculation unit is programmable to generate a first subset of pixels by filtering using the rendered samples and a second subset of the output pixels by interpolating using the first subset of pixels and / or the rendered samples. By interpolating a subset of the output pixels, the graphics system may be able to operate at higher resolutions and / or refresh rates since filtering of the samples is computationally intensive. Any ratio of the number of first subset of pixels to the number of the second subset of pixels may be used, and furthermore, a different ratio may be used for different regions of the display screen. A higher ratio of the number of first subset of pixels to the number of second subset of pixels may be used for regions of the screen where a higher quality image is desired and a lower ration may be used for regions where a lower quality image may be sufficient. For example, a higher quality image may be desired close to and around the foveation point where the eye of an observer is focused.

The invention relates to a parallel model processing method based on multiple graphics processing units (GPUs). The method includes the steps: creating multiple Workers used for respectively controlling multiple Worker Groups in a central processing unit (CPU), wherein each Worker Group comprises the GPUs; binding each Worker with one corresponding GPU; loading one Batch of training data from a nonvolatile memory into a GPU video memory corresponding to one Worker Group; transmitting data, needed by the GPUs for data processing, among the GPUs corresponding to one Worker Group in a Peer to Peer manner; controlling the GPUs to perform data processing in parallel through the Workers. By the method, efficiency of parallel data processing of the GPUs can be improved. Besides, the invention further provides a parallel data processing device.

The hybrid fabric interconnect includes multiple data channels, including programmable virtual data channels. The virtual data channels carry multiple traffic classes of packet-based messages. The virtual data channels and multiple traffic classes may be assigned one of multiple priorities. The virtual data channels may be arbitrated independently. The hybrid fabric is scalable and can support multiple topologies, including multiple stacked integrated circuit topologies.

A method of server site rendering 3D images on a server computer coupled to a client computer wherein the client computer instructs a server computer to load data for 3D rendering and sends a stream of rendering parameter sets to the server computer, each set of rendering parameters corresponding with an image to be rendered; next the render computer renders a stream of images corresponding to the stream of parameter sets and the stream of images is compressed with a video compression scheme and sent from the server computer to the client computer where the client computer decompresses the received compressed video stream and displays the result in a viewing port. The rendering and communication chain is subdivided in successive pipeline stages that work in parallel on successive rendered image information.

Systems and methods in accordance with embodiments of this invention perform depth regularization and semiautomatic interactive matting using images. In an embodiment of the invention, the image processing pipeline application directs a processor to receive (i) an image (ii) an initial depth map corresponding to the depths of pixels within the image, regularize the initial depth map into a dense depth map using depth values of known pixels to compute depth values of unknown pixels, determine an object of interest to be extracted from the image, generate an initial trimap using the dense depth map and the object of interest to be extracted from the image, and apply color image matting to unknown regions of the initial trimap to generate a matte for image matting.

Novel method and system for distributed database ray-tracing is presented, based on modular mapping of scene-data among processors. Its inherent properties include scattering data among processors for improved load balancing, and matching between geographical proximity in the scene with communication proximity between processors. High utilization is enabled by unique mechanism of cache sharing. The resulting improved performance enables deep level of ray tracing for real time applications.

In one embodiment, a technique for controlling one or more devices within a physical room of a structure is provided. One or more devices in the structure are coupled, either directly or indirectly, to a programmable multimedia controller configured to issue control commands which, when implemented, change the state of the devices. A virtual room-based user interface is displayed on a display screen. The virtual room-based user interface may include one or more virtual rooms, each virtual room including a substantially photo-realistic depiction of a portion of the structure, including substantially photo-realistic depictions of one or more devices located within the portion of the structure. In response to the selection of a particular substantially photo-realistic visual depiction, the programmable multimedia controller may issue control commands which, when implemented, change the state of a particular device. The appearance of the particular virtual room may be updated to reflect the changed state.
