Abstract: Techniques are disclosed for automatically calibrating content shown on an electronic display. According to certain embodiments, a picture of the display is taken while a calibration image is shown on the display. The picture is then analyzed to determine whether any adjustments need to be made. The analysis can, for example, include a comparison between the picture of the calibration image and a stored calibration image. If it is determined an adjustment needs to be made to correct how content is shown on the display, an adjustment is made accordingly.

Abstract: The disclosure relates to systems and methods for altering perception of virtual or game content in a virtual space based on one or more attribute levels. The perception of some virtual or game content may not be altered. Thus, the depiction of some content is altered while other content is not. A system may alter the depiction of game content based on attributes of an entity and/or based on which entity is to perceive the game content. The different depictions of game content may be provided to the same entity at different times and/or different perceptions of game content may be provided to different entities. Thus, a rich interface may be provided that differentially depicts game content based on attribute levels and/or the entity that is to perceive the game content.

Abstract: An embodiment provides a timeline upon which a playhead indicator is moved or positioned. Changes to a displayed graph that are within a predetermined interval of the playhead indicator's time position are shown graphically on or near the graph. Actor icons are positioned on or near the displayed graph. The actor icons correspond to different entities (e.g., a person, group, organization, software agent, etc.) that has made a change to the graph. Change indicators both on the timeline and in association with the actor icons can be color-coded to indicate addition, deletion, modification or other operations to graph items or to other objects being displayed.

Abstract: In one embodiment, a movable area, referred to as a “lens,” on a graph display allows the user to preview the zoom level of the graph. When a node, line or other item in the graph is in the area of the lens, then the item can be shown at a different zoom level than rest of the graph. In particular embodiments, a heuristic algorithm can be used to dynamically determine the visual representation of a node when in the lens as unique from the depiction of the node when the node is outside of the lens. Operations can be made to the graph items within the lens such as adding, moving, deleting, or connecting items, etc. Other features are described.

Abstract: In various embodiments, a screen image may be divided into rectangles, and a capture component may track changed rectangles and capture the screen upon receiving an indication. For small screen updates, the capture rate may be set to ˜30 captures per second to provide a lower latency. As the screen update size increases, the capture rate may be decreased to match an allocated bandwidth. The capture rate may be increased when available bandwidth increases and decreased as bandwidth decreases. For example, the capture rate may be decreased when downstream back pressure meets predefined criteria. The capture rate change may be effected gradually to avoid jerks and jumps. Varying the capture rate by also enable audio/video synchronization with varying bandwidth variations. Some embodiments may be extended to multiple monitor solutions.

Abstract: One embodiment of the present invention sets forth a technique for placing texture barrier instructions within a thread program to advantageously enable efficient and correct operation of the thread program. A thread program compiler statically determines a pending request count needed to progress beyond a particular texture barrier instruction, which blocks execution of subsequent instructions that depend on previously requested data. Each instance of the thread program blocks execution at the barrier instruction until a pending request count condition is satisfied. This technique may advantageously reduce power consumption in a graphics processing unit by eliminating power consumption associated with conventional, generalized scoreboard resources.

Abstract: A system for performing graphics processing is disclosed. A dependency graph comprising interconnected nodes is accessed. Each node has output attributes and the dependency graph receives input attributes. A first list is accessed, which includes a dirty status for each dirty output attribute of the dependency graph. A second list is accessed, which associates one of the input attributes with output attributes that are affected by the one input attribute. A third list is accessed, which associates one of the output attributes with output attributes that affect the one output attribute. An evaluation request for a requested output attribute is received. A set of output attributes are selected for evaluation based on being specified in the first list as dirty and being specified in the third list as associated with the requested output attribute. The set of output attributes are evaluated.

Abstract: Methods and systems are provided for efficiently identifying map tiles of a raised-relief map to retrieve from a server. An electronic device can use estimates of height(s) for various region(s) of the map to determine map tiles that are likely viewable from a given position of a virtual camera. The device can calculate the intersection of the field of view of the virtual camera with the estimated heights to determine a location of the map tiles (e.g., as determined by a 2D grid) needed. In this manner, the electronic device can retrieve, from a map server, the map tiles needed to display the image, without retrieving extraneous tiles that are not needed. Identifying such tiles can reduce the amount of data to be sent across a network and reduce the number of requests for tiles, since the correct tiles can be obtained with the first request.
