20120306912 | Global Composition System - A global composition system is described. In one or more implementations, the global composition system may be configured to perform rendering for a plurality of applications. For example, the global composition system may be configured to expose one or more application programming interfaces (APIs) that are accessible to the applications. The APIs may then be used to cause a single composition engine to perform the rendering for the plurality of applications. The use of a single composition engine may be used to support a variety of different functionality, such as to perform efficient rendering by knowing what elements are provided by each of the applications and how those items relate for rendering to a display device. | 12-06-2012 |
20130033511 | COMPOSING STEREO 3D WINDOWED CONTENT - A technique for generating content for a stereo 3D display buffer having both stereo 3D graphic objects and non-stereo 3D graphic objects that may be utilized to render stereo 3D content onto one or more windows of a display. The technique incorporates content from stereo 3D application frame buffers into a composition tree that represents the graphic objects in each window displayed on a computing device. At each refresh cycle, the composition tree is traversed to generate content for a stereo 3D display buffer that is then used to draw one or more windows onto a display. | 02-07-2013 |
20130063445 | Composition System Thread - Composition system thread techniques are described. In one or more implementations, a composition system may be configured to compose visual elements received from applications on a thread that is executed separately than a user interface thread of the applications. As such, the composition system may execute asynchronously from a user interface thread of the application. Additionally, the composition system may be configured to expose one or more application programming interfaces (APIs) that are accessible to the applications. The APIs may be used for constructing a tree of objects representing the operations that are to be performed to compose one or more bitmaps. Further, these operations may be controlled by several API visual properties to allow applications to animate content within their windows and use disparate technologies to rasterize such content. | 03-14-2013 |
20130063482 | APPLICATION PROGRAMMING INTERFACE FOR A BITMAP COMPOSITION ENGINE - An application programming interface is provided by an operating system that includes a direct composition engine. The composition engine maintains a data structure that represents the display objects to be rendered on a desktop display. The application programming interface allows an application to write data to the data structure to update the display object, such as a window, for the application. Thus, multiple applications can update their respective display objects in this data structure. The direct composition engine is an operating system level process, presented to user-level processes as a service of the operating system. By having an operating system level process, performance standards can be maintained. The application programming interface also allows applications to provide display information that can be rendered more efficiently by the operating system than by the application. | 03-14-2013 |

These techniques include support of initialization and batching of updates, use of updates and lookaside lists, use of gutters, blending and BLT operations, surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and occlusion management techniques. | 12-05-2013 |
20130321454 | Virtual Surface Lookaside Lists and Gutters - Virtual surface techniques are described. These techniques include support of initialization and batching of updates, use of updates and lookaside lists, use of gutters, blending and BLT operations, surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and occlusion management techniques. | 12-05-2013 |
20130321455 | Virtual Surface Rendering - Virtual surface techniques are described. These techniques include support of initialization and batching of updates, use of updates and lookaside lists, use of gutters, blending and BLT operations, surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and occlusion management techniques. | 12-05-2013 |
20130321471 | Virtual Surface Compaction - Virtual surface update and composition techniques are described. These techniques include support of initialization and batching of updates, use of updates and lookaside lists, use of gutters, blending and BLT operations, surface optimization techniques such as push down as well as enumeration and clumping, mesh usage, and occlusion management techniques. | 12-05-2013 |
20140333637 | Shared Compositional Resources - Shared compositional resources are described. In one or more implementations, a global composition system may be configured to perform rendering for a plurality of processes, e.g., applications. For example, the global composition system may be configured to expose one or more application programming interfaces (APIs) that are accessible to the processes. The APIs may then be used to cause a single composition engine to perform the rendering for the plurality of applications. Thus, the single composition engine may be leveraged to support a variety of functionality, such as to manage sharing of compositional resources by a plurality of processes. This sharing may be performed in a variety of ways, which may include use of a writer/reader paradigm. | 11-13-2014 |
20140362122 | Input Object for Routing Input for Visual Elements - Techniques for an input object for routing input for visual elements are described. In at least some embodiments, a region of a display area includes multiple graphic elements that can be generated and/or managed by different graphics functionalities. For instance, a graphical user interface (GUI) for an application can include a primary window and visual elements within the primary window, such as banners, control buttons, menus, Tillable fields, and so forth. In at least some embodiments, the primary window of the GUI can be managed by a first graphics functionality, while one or more visual elements within the primary window can be managed by a second graphics functionality. In accordance with one or more embodiments, an input object is employed to route input to visual elements to a graphics functionality responsible for managing the visual elements. | 12-11-2014 |
