摘要： A method and system for rendering a desktop on a computer using a composited desktop model operating system are disclosed. A composited desktop window manager, upon receiving base object and content object information for one or more content objects from an application program, draws the window to a buffer memory, and takes advantage of advanced graphics hardware and visual effects to render windows based on content on which they are drawn. The frame portion of each window may be generated by pixel shading a bitmap having the appearance of frosted glass based on the content of the desktop on top of which the frame is displayed. Legacy support is provided so that the operating system can draw and render windows generated by legacy applications to look consistent with non-legacy application windows.

摘要： A method and system for rendering a desktop on a computer using a composited desktop model operating system are disclosed. A composited desktop window manager, upon receiving content information from application programs, draws the window to a buffer memory for future reference, and takes advantage of advanced graphics hardware and visual effects to render windows based on content on which they are drawn. The windows may also be rendered based on environment variables including virtual light sources. The frame portion of each window may be generated by pixel shading a bitmap having the appearance of frosted glass based on the content of the desktop on top of which the frame is displayed. Legacy support is provided so that the operating system can draw and render windows generated by legacy applications to look consistent with non-legacy application windows.

摘要： Described is an adaptive scheduler associated with a desktop window manager that dynamically controls the rate at which graphics frames are composed. Values corresponding to performance when composing a frame are measured, and the frame composition rate is adjusted as necessary based on the values. The measured data is sampled to provide smooth adjustments. The sampled data is evaluated as to whether the current frame rate is too slow, too fast, or acceptable. If too slow, the frame rate may increased relative to the refresh rate, while if too fast, the frame rate is decreased relative to the refresh rate. In one implementation, the frame rate is too fast if a count of missed frames achieves a missed threshold value, or if a count of late frames achieves a late threshold value. The frame rate is too slow if a count of early frames exceeds an early threshold value.
摘要翻译： 描述了与桌面窗口管理器相关联的自适应调度器，其动态地控制组合图形帧的速率。 测量与构成帧时的性能对应的值，根据该值根据需要调整帧合成率。 测量的数据被采样以提供平滑的调整。 评估采样数据是否当前帧速率太慢，太快或可接受。 如果太慢，帧速率可能相对于刷新率增加，而如果太快，则帧速率相对于刷新率降低。 在一个实现中，如果错过的帧的计数达到错过的阈值，或者如果后期帧的计数达到迟到的阈值，则帧速率太快。 如果早期帧的计数超过早期阈值，则帧速率太慢。

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： The visual output of legacy child windows intended for display on a non-legacy parent are redirected to an off-screen bitmap buffer. A display component having enhanced visual functionality processes the output of the legacy child window with any of a number of visual effects. The display component composes the parent window by combining the non-legacy visual output with the processed output of the legacy child window. In this way, visual enhancements that have been technologically unavailable to the legacy child windows may be applied to the legacy child windows when used in combination with a new-technology parent window.

摘要： An application program interface may be used to construct a three-dimensional (3D) scene of 3D models defined by model 3D objects. The interface has one or more group objects and one or more leaf objects. The group objects contain or collect other group objects and/or leaf objects. The leaf objects may be drawing objects or an illumination object. The group objects may have transform operations to transform objects collected in their group. The drawing objects define instructions to draw 3D models of the 3D scene or instructions to draw 2D images on the 3D models. The illumination object defines the light type and direction illuminating the 3D models in the 3D scene. A method processes a tree hierarchy of computer program objects constructed with objects of the application program interface. The method traverses branches of a 3D scene tree hierarchy of objects to process group objects and leaf objects. The method detects whether the next unprocessed object is a group object of a leaf object. If it is a leaf object, the method detects whether the leaf object is a light object or a drawing 3D object. If the leaf object is a light object, the illumination of the 3D scene is set. If a drawing 3D object is detected, a 3D model is drawn as illuminated by the illumination. The method may also performs a group operation on the group of objects collected by a group object.

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： In order to render a primitive, the primitive is subdivided into trapezoids and triangles. The subdivision occurs using scanline-aligned lines. These simple scanline-aligned regions are further subdivided so that the primitive is divided into simple scanline-boundaried trapezoids and other complex scan shapes. The simple scanline-boundaried trapezoids are rasterized. One rasterization method uses a texture map containing slope-based coverage information to edge areas. Gouraud shading may be used to provide the anti-aliasing effects on the scanline-boundaried trapezoids. The simple scanline-boundaried trapezoids may also be rasterized using a software rasterizer. Complex scans are rasterized using a software rasterizer. As data is already rasterized, it is thereby efficiently transferred to the GPU.
