摘要： Various technologies and techniques are disclosed for controlling a shader declaratively. A declarative programming model enables declarative statements to be used that control an instantiation of a shader in a declarative presentation framework. A shader-based effect that was specified declaratively is instantiated programmatically for rendering graphic effects for a software application. Declarative statements are sent to a shader processor to enable a shader to render the graphical effect customizations for the software application. A method is also described for utilizing a declarative programming model as a multiple pass effect that controls and encapsulates a set of shaders to be run during a multiple pass operation.

摘要： A curve drawing system is described herein that rasterizes arc splines in the GPU of a computer for cubic Bezier drawing of strokes and thin features. The curve drawing system first converts a cubic Bezier representation into an arc spline representation. Then the curve drawing system uses a similar approach to Loop/Blinn modified to cause the pixel shader to perform a point-in-circular-arc test instead of a point-in-Bezier test. Calculating arc radius is a much simpler operation than the alternatives and can be easily and efficiently performed by the pixel shader. Since the stroke of an arc spline is also an arc spline, the drawing system provides a resolution-independent representation of strokes. Thus, the curve drawing system allows several previously difficult graphical features to be efficiently drawn by readily available legacy hardware and used in software programs that are designed to run on a wide variety of hardware.

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.
摘要翻译：智能缓存数据结构和机制，通过对象和表示图形信息的数据存储视觉信息。数据结构通常与智能地控制如何填充和使用其中的视觉信息的机制相关联。可以遍历高速缓存数据结构以进行直接呈现，或者遍历以将视觉信息预处理成另一个实体的指令流。许多数据通常没有对其的外部参考，从而使得能够处理存储在数据结构中的更多信息以节省资源。用于更新数据结构的交易/批量化模型使得能够对数据结构进行外部修改，而不会中断从数据结构的读取，并且使得接收的变化被原子地实现。提供了一种方法和机制来回调应用程序，以便根据需要创建或重新创建数据结构的一部分，以节省资源。

摘要： An extensible editor allows integration of extensions that modify the editor's default behavior and provide customized feedback to users. The editor includes an event routing model that works to decrease the occurrence of conflicts between the editor and extensions and between extensions. Upon the occurrence of an event, the editor routes the event to each extension before the editor's default handling of the event occurs. When an extension responds to an event, the extension may “consume” the event by indicating to the editor not to allow further processing of the event. After an event has been pre-processed by each extension, the default editor acts on the event. The editor then routes the event to each extension again, to allow each extension to process the event after the default editor has acted.

摘要： Systems and methods are provided for providing anti-aliasing by introducing a falloff area around a graphics object to be rendered. The falloff area is shaded, using Gouraud shading or texture mapping to reduce the aliasing effects of the graphics object. The outside edge of the falloff area is set to be fully transparent, and the inside edge to an opacity matching the outer edge of the graphics object being rendered. To counteract bloating effects, the graphics object is shrunk by half the width of the falloff area. While the width of the falloff area may vary, generally, the width of the falloff area stays constant. In one embodiment, this width corresponds to the edge or diagonal of the square area mapped to each pixel.
摘要翻译：提供了系统和方法，通过在要呈现的图形对象周围引入衰减区域来提供抗锯齿。衰减区域是阴影的，使用Gouraud阴影或纹理映射来减少图形对象的混叠效应。衰减区域的外部边缘被设置为完全透明，并且内部边缘变为与呈现的图形对象的外边缘匹配的不透明度。为了抵消腹胀效应，图形对象缩小到衰减区域宽度的一半。虽然衰减区域的宽度可能变化，但一般来说，衰减区域的宽度保持不变。在一个实施例中，该宽度对应于映射到每个像素的方形区域的边缘或对角线。

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.
