  • Publication number: 20200058152
    Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.

  • Patent number: 9868254
    Abstract: Systems, computer readable media, and methods for printing of 3D objects in color are disclosed. In general, a 3D object may be produced and colored by a 3D printer using the same digital 3D model. The digital model for a desired 3D object may be revised to include a process for coloring the object by the 3D printer. In one embodiment, this may involve coloring to the object after it has been made. In an alternative embodiment, color may be added as the object is being made. Because the 3D model provides knowledge of the surface, contours and all the coordinates of the 3D object being printed, the object can be colored using the same digital model.

  • Patent number: 9189253
    Abstract: Systems, methods, and computer readable media for implementing reentrant compositing window manager applications are described. In general, techniques are disclosed for using a second application to composite portions of hierarchically structured objects and the window manager to composite certain other portions of the same object. More particularly, a window manager application may be used to composite objects of a first type (e.g., application backing store bitmaps) and then call or invoke a second application to composite objects of a second type (e.g., hierarchically structured objects). The second type of object includes information (e.g., a reference) of the composite window manager's output buffer at the time the second application was invoked.

  • Patent number: 9092911
    Abstract: Methods and apparatus for a predictive rendering component that may generate a rendering of a character based at least in part on predictive information regarding the background into which the character is to be rendered. Using such predictive information, the predictive rendering component may produce a rendering of a character that blends into the character background more smoothly than if the predictive background information were not used. In this way, the predictive rendering component improves upon previous implementations of font smoothing.

  • Patent number: 9013512
    Abstract: Systems, methods, and computer readable media for dynamically setting an executing application's display buffer size are described. To ameliorate display device overscan operations, the size of an executing application's display buffer may be set based on the display device's extent and a display mode. In addition, contents of the executing application's display buffer may be operated on as they are moved to a frame buffer based on the display mode. In one mode, for example, display buffer contents may be scaled before being placed into the frame buffer. In another mode, a black border may be placed around display buffer contents as it is placed into the frame buffer. In yet another mode, display buffer contents may be copied into the frame buffer without further processing.

  • Patent number: 8687007
    Abstract: Exemplary embodiments of methods, apparatuses, and systems for seamlessly migrating a user visible display stream sent to a display device from one rendered display stream to another rendered display stream are described. For one embodiment, mirror video display streams are received from both a first graphics processing unit (GPU) and a second GPU, and the video display stream sent to a display device is switched from the video display stream from the first GPU to the video display stream from the second GPU, wherein the switching occurs during a blanking interval for the first GPU that overlaps with a blanking interval for the second GPU.
