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 |
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 |
20130063456 | Buffer Display Techniques - Buffer display techniques are described. In one or more implementations, at least part of an off-screen buffer is rasterized by an application to generate an item for display by the computing device. One or more communications are formed that describe the part of the off-screen buffer which contains the item that is to be copied to update an onscreen buffer. | 03-14-2013 |
20130067502 | Atlasing and Virtual Surfaces - Atlasing and virtual surface techniques are described. In one or more implementations, virtual surface functionality is exposed by an operating system for access by one or more applications of the computing device. A virtual surface is created in response to a request from the one or more applications to be used to render visuals for display by a display device. The virtual surface is allocated in memory of the computing device by the exposed virtual surface functionality to have an area that is larger than an area to be used to display the visuals from the one or more applications. | 03-14-2013 |
20130321453 | Virtual Surface Allocation - 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 |
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 |
20140344729 | PRIMITIVE-BASED COMPOSITION - Primitive-based composition techniques are described. In one or more implementations, a 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. Further, the composition engine may support the use of primitives, which include one or more rendering instructions and thus an element associated with a visual to be rendered may be something other than a bitmap. | 11-20-2014 |
20150035844 | Buffer Display Techniques - Buffer display techniques are described. In one or more implementations, at least part of an off-screen buffer is rasterized by an application to generate an item for display by the computing device. One or more communications are formed that describe the part of the off-screen buffer which contains the item that is to be copied to update an onscreen buffer. | 02-05-2015 |
