摘要： A visual tree structure as specified by a program is constructed and maintained by a visual system's user interface thread. As needed, the tree structure is traversed on the UI thread, with changes compiled into change queues. A secondary rendering thread that handles animation and graphical composition takes the content from the change queues, to construct and maintain a condensed visual tree. Static visual subtrees are collapsed, leaving a condensed tree with only animated attributes such as transforms as parent nodes, such that animation data is managed on the secondary thread, with references into the visual tree. When run, the rendering thread processes the change queues, applies changes to the condensed trees, and updates the structure of the animation list as necessary by resampling animated values at their new times. Content in the condensed visual tree is then rendered and composed. Animation and a composition communication protocol are also provided.

摘要： A media integration layer including an application programming interface (API) and an object model allows program code developers to interface in a consistent manner with a scene graph data structure in order to output graphics. Via the interfaces, program code adds child visuals to other visuals to build up a hierarchical scene graph, writes Instruction Lists such as geometry data, image data, animation data and other data for output, and may specify transform, clipping and opacity properties on visuals. The media integration layer and API enable programmers to accomplish composition effects within their applications in a straightforward manner, while leveraging the graphics processing unit in a manner that does not adversely impact normal application performance. A multiple-level system includes the ability to combine different media types (such as 2D, 3D, Video, Audio, text and imaging) and animate them smoothly and seamlessly.

摘要： Performing primitive composition within a user interface thread, enhancing the ability to scale a user interface framework to computing devices having limited resources. In one or more embodiments, a user interface thread walks a user interface hierarchy that describes elements of a program's user interface and directly generates static Graphics Processing Unit (GPU) data structures representing at least a portion of the user interface hierarchy. The user interface thread passes the static GPU data structures to a composition thread, which uses these static GPU data structures during generation of a plurality of video frames. This includes the composition thread, based on the static GPU data structures, sending GPU data and GPU commands for the plurality of video frames to a GPU for rendering.

摘要： Architecture that expresses scene composition and animation in a form that can run entirely on the graphics processing unit (GPU). The architecture stores retained graph information (e.g., scene graph and animation information) as texture information, and uses shaders (e.g., vertex and pixel) to evaluate time information, evaluate animation, evaluate transforms, and rasterize paths. Additionally, the architecture provides the ability to compute animation positions and redraw entirely on the GPU without per primitive CPU intervention.

摘要： Rendering different types of graphical content using a single primitive type. Embodiments enable graphical elements of different content types representing a scene to be rendered as a batch based on the single primitive type, thereby reducing data transfer and improving processing performance. For example, each graphical element in a batch of graphical elements can rendered based modifications to instances of a template shape, which represents a single primitive type usable for rendering different types of graphical content. The modifications to each instance can include modifying the instance according transformation data, clip data, and/or width and height data to position the instance in a scene, and filling the modified instance according to one or more of shape or brush data corresponding to the graphical element.

摘要： An intelligent caching data structure and mechanisms for storing visual information via objects and data representing graphics information. The data structure is generally associated with mechanisms that intelligently control how the visual information therein is populated and used. The cache data structure can be traversed for direct rendering, or traversed for pre-processing the visual information into an instruction stream for another entity. Much of the data typically has no external reference to it, thereby enabling more of the information stored in the data structure to be processed to conserve resources. A transaction/batching-like model for updating the data structure enables external modifications to the data structure without interrupting reading from the data structure, and such that changes received are atomically implemented. A method and mechanism are provided to call back to an application program in order to create or re-create portions of the data structure as needed, to conserve resources.

摘要： A parameterized scene graph provides mutable (animated) values and parameterized graph containers such that an application program or the like can selectively change certain aspects of the scene graph description while leaving other aspects intact, and also reuse portions of the scene graph with different parameters. To this end, mutable values are provided, which provide the higher level code with hooks into the scene graph enabling the scene description to be changed. The mutable values may be varied over time to provide animation. A parameterized graph container is also described that enables a scene graph portion to be templatized for reuse throughout a scene in a generic way. In this manner, a single parameterized graph container may be efficiently reused in a scene graph, with different values for its parameters.
