Abstract: A technique for efficiently rendering path images tessellates path contours into triangle tans comprising a set of representative triangles. Topology of the set of representative triangles is then optimized for greater rasterization efficiency by applying a flip operator to selected triangle pairs within the set of representative triangles. The optimized triangle pairs are then rendered using a path rendering technique, such as stencil and cover.

Abstract: Techniques for performing clipping of graphics primitives 60 with respect to a clipping boundary 65 are described. The clipping step 10 may be performed separately for each tile of a graphics frame to be rendered, after a primitive list for the tile has been read from a primitive memory 38. Clipping may be performed only for larger primitives whose size exceeds a given threshold. Clipping of a primitive 60 to the clipping boundary 65 may be performed inexactly so that only a single clipped primitive is generated which may extend beyond the clipping boundary. A clipped primitive generated by clipping may be used for a depth function calculation of a primitive setup operation and not for an edge determination.

Abstract: Methods, systems, computer-readable media, and apparatuses for constructing a representation of a planar object are presented. In some embodiments, techniques for constructing a representation of a planar object are disclosed. According to some embodiments, a method for constructing a representation of a planar object may include obtaining a depth image of a physical scene as captured from a viewing position. The depth image may comprise a plurality of depth values and corresponding to a plurality of points in the physical scene. The method may further include identifying a planar surface along which the planar object is estimated to be positioned. Furthermore, the method may include constructing a support map. Moreover, the method may include constructing an occlusion map, the occlusion map indicating portions of the planar surface where the planar object is missing. Subsequently, the method may include constructing a representation of at least one boundary of the planar object, using the occlusion map.

Abstract: The present disclosure provides a method for cropping one or more files in freeform using transparent or non-transparent layers. Specifically, the embodiments allow a user to crop a file with irregular/freeform boundaries while using a plurality of transparent or non-transparent layers that overlay the original file. The transparent layers overlap the image data for cropping, so that the finalized cropped image may be copied, pasted, or imported into another document while leaving the original file unaltered. The cropped portion of the image may also be sent or emailed by the user.

In the communication method, motion information is determined using a motion image obtained by photographing a user's motion indicating the user's request in relation to an opposite party, distance information indicating the distance between the user who is moving and the 3D image display device is determined, and then, the user's request is determined based on the motion information and the distance information.

Abstract: Various improvements may lead to reducing or avoiding artifacts in curved planar reformation imaging. The source of voxels used in projection rendering may be verified to be from the vessels rather than intervening anatomy. To make the check more rapid, a hierarchal data structure may be used. Rather than using the vessels, geometric forms fit to the vessels may be used. Processing with geometric forms may be more rapid than a fine mesh or surface. Since tubular structures have a predictable change over length, the geometric forms or the vessel data itself may be filtered with a monotonicity constraint. Instead of using planes for segments based on the lumen or center line, a convex hull around the tubular structures is formed for the curved planar reformation.

Abstract: A real time 3D survey site modeler is disclosed. One embodiment includes a survey data collector to collect survey data for a location and obtain information for each object that is surveyed. In addition, a 3D model creator receives the collected survey data and creates a 3D model of the world being surveyed in real time.

Abstract: Aspects include API interfaces for interfacing shaders with other components and/or code modules that provide ray tracing functionality. For example, API calls may allow direct contribution of light energy to a buffer for an identified pixel, and allow emission of new rays for intersection testing alone or in bundles. The API also can provide a mechanism for associating arbitrary data with ray definition data defining a ray to be tested through a shader using the emit ray call. The arbitrary data is provided to a shader associated with an object that is identified subsequently as having been intersected by the ray. The data can include code, or a pointer to code, that can be used by or run after the shader. The data also can be propagated through a series of shaders, and associated with rays instantiated in each shader. Recursive shaders can be recompiled as non-recursive shaders interfacing with API semantics according to the description.

Abstract: Systems and methods are described for performing spatial and temporal compression of deformable mesh based representations of 3D character motion allowing the visualization of high-resolution 3D character animations in real time. In a number of embodiments, the deformable mesh based representation of the 3D character motion is used to automatically generate an interconnected graph based representation of the same 3D character motion. The interconnected graph based representation can include an interconnected graph that is used to drive mesh clusters during the rendering of a 3D character animation. The interconnected graph based representation provides spatial compression of the deformable mesh based representation, and further compression can be achieved by applying temporal compression processes to the time-varying behavior of the mesh clusters.

Abstract: Techniques are disclosed for stably simulating stylized curly hair that address artistic needs and performance demands, both found in the production of feature films. To satisfy the artistic requirement of maintaining a curl's helical shape during motion, a hair model is developed based upon an extensible elastic rod. A method is provided for stably computing a frame along a hair curve for stable simulation of curly hair. The hair model introduces a new type of spring for controlling the bending and twisting of a curl and another for maintaining the helical shape during extension. The disclosed techniques address performance concerns often associated with handling hair-hair contact interactions by efficiently parallelizing the simulation. A novel algorithm is presented for pruning both hair-hair contact pairs and hair particles.

Abstract: A web server receives a request from a client specifying a location and a bounding area. A mapping engine creates a tile grid centered at the specified location. A seed tile is created, including or adjacent to the center location. The web server creates a resource identifier for each tile in the tile grid, and returns the tile grid including the resource identifiers to the client. The resource identifier for each tile includes the location of the seed tile and a position offset for the tile relative to the seed tile, in one embodiment specified in units of northward and eastward movement. The client requests tiles from the system using the resource identifiers previously provided by the system. Upon receiving the request, the mapping engine dynamically renders each requested tile using map data from the map database, and the web server returns the dynamically-generated tiles to the requesting client.

Abstract: A see-through head-mounted display (HMD) device provides an augmented reality image which is associated with a real-world object, such as a picture frame, wall or billboard. Initially, the object is identified by a user, e.g., based on the user gazing at the object for a period of time, making a gesture such as pointing at the object and/or providing a verbal command. The location and visual characteristics of the object are determined by a front-facing camera of the HMD device, and stored in a record. The user selects from among candidate data streams, such as a web page, game feed, video or stocker ticker. Subsequently, when the user is in the location of the object and looks at the object, the HMD device matches the visual characteristics to the record to identify the data stream, and displays corresponding augmented reality images registered to the object.

Abstract: Systems and approaches provide for a user interface (UI) that is based on the position of a user's head with respect to a computing device. In particular, a three-dimensional (3D) rendering engine that is independent of a particular operating system can be integrated with the UI framework of the operating system such that a window or view into a fully 3D world can be drawn using the independent renderer. This window or view can then be laid out and manipulated in a manner similar to other elements of the UI framework. Further, the 3D window or view can be configured to monitor head tracking data as input events to the UI framework. The contents of the window or view can be redrawn or rendered based on the head tracking data to simulate three-dimensionality of the content.
