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.

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： 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： A system and method for processing and rendering multiple layers of a two-dimensional scene. A system provides a mechanism to determine a number of scene surfaces and a mapping between scene layers and scene surfaces. The mechanisms may include combining and aggregating areas of layers to create one opaque surface, aggregating non-overlapping semi-transparent opaque areas of layers, or creating surfaces from overlapping semi-transparent surfaces. Moving objects are accommodated, so that layers below a moving object may be rendered properly in frames where the moving object is above the layer and frames where the moving object is not above the layer, for each pixel.

摘要： Hybrid architecture of supersampling and computing distance from a feature edge or Bezier evaluation to address thin feature support in graphics systems. To avoid missing some features the technique creates a supersampling of a small number of supersamples to pick up the thin features. By supersampling, samples can be produced on both sides of a thin feature, which causes thin features to be detectable by some pixel. Now that the thin features hit some pixel, the quality is achieved by a distance-from-edge approach. For example, the technique can supersample four times in combination with the distance-from-edge approach, produce another four samples there resulting in a 16-sample result.

摘要： Described is a rasterizer that processes the graphics primitives of a frame's image to build an array of entries representing which scanlines are affected by which graphics primitives. When built, the array is then referenced to draw the data of more or more combined primitives, e.g., on a scanline-by-scanline basis. Each scanline may be divided into segments defined by the edges of the primitives that affect the scanline, with the segments drawn based on each primitive's drawing data, e.g., including brush information and drawing order. Aliased and anti-aliased rasterizing are described, as is three-dimensional triangle data, and applying effects to groups of primitives.

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： 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 method and system for anti-aliased rasterization of objects. From a particular viewpoint of an object represented by shapes, a shape is selected having an edge on a silhouette of the object. An edge geometry is created at the edge of the shape that is on the silhouette of the object. The edge geometry is rendered. Either the shape is rendered after the edge geometry is rendered with the depth test set so as to not allow portions of the shape to overlap the edge geometry, or the shape itself is modified to remove any portion that overlaps the edge geometry. This may be repeated for each edge of each shape that lies on the silhouette of the object.
