    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.

    摘要翻译： 参数化场景图提供可变（动画）值和参数化图形容器，使得应用程序等可以选择性地改变场景图描述的某些方面，同时使其他方面保持不变，并且还重用具有不同参数的场景图的部分。 为此，提供了可变值，其将较高级代码提供到场景图中的钩子，使得能够改变场景描述。 可变值可随时间而变化以提供动画。 还描述了参数化图形容器，其使场景图形部分被模板化以便以通用方式在整个场景中重用。 以这种方式，单个参数化图形容器可以在场景图中有效地重新使用，其参数具有不同的值。

    摘要： A multiple-level graphics processing system and method (e.g., of an operating system) for providing improved graphics output including, for example, smooth animation. One such multiple-level graphics processing system comprises two components, including a tick-on-demand or slow-tick high-level component, and a fast-tick (e.g., at the graphics hardware frame refresh rate) low-level component. In general, the high-level, less frequent component performs computationally intensive aspects of updating animation parameters and traversing scene data structures, in order to pass simplified data structures to the low-level component. The low-level component operates at a higher frequency, such as the frame refresh rate of the graphics subsystem, to process the data structures into constant output data for the graphics subsystem. The low-level processing includes interpolating any parameter intervals as necessary to obtain instantaneous values to render the scene for each frame of animation.

    摘要： Described are mechanisms and techniques for providing interoperability between two different graphics technologies. An application includes windows of two types, a legacy type and a new type. A graphics system includes components that support each of the two types. Interoperability is achieved by creating legacy structures associated with any windows of the new type. A mapping is created that associates the legacy structures with the windows of the new type. Rendering of legacy windows is performed by a first graphics technology, and rendering of new windows is performed by a second graphics technology. The distinction between the two types of windows is noted by the existence of the legacy structures.

    摘要： A graphical display animation system is disclosed that supports timed modification of element property values of elements within a graphical display. The animation system utilizes a display structure for maintaining a set of elements corresponding to displayed objects within a graphically displayed scene. The elements include a variable property value. The animation system also utilizes a property system that maintains properties associated with elements maintained by the display structure. The properties include dynamic properties that are capable of changing over time—and thus affecting the appearance of the corresponding element on a graphical display. The animation system includes animation classes, from which animation objects are instantiated and associated with an element property at runtime. The animation object instances provide time varying values affecting values assigned to the dynamic properties maintained by the property system.
