摘要： In a raster stage of a graphics pipeline, a method for rasterizing non-rectangular tile groups. The method includes receiving a graphics primitive for rasterization in a raster stage of a graphics processor. The graphics primitive is rasterized at a first level by generating a non-rectangular footprint comprising a set of pixels related to the graphics primitive. The graphics primitive is then rasterized at a second level by accessing the set of pixels and determining covered pixels out of the set of pixels. The raster stage subsequently outputs the covered pixels for rendering operations in a subsequent stage of the graphics processor.

摘要： Stippled lines are drawn by evaluating a distance function for a set of points within the area of a stippled line. The distance function gives a distance value proportional to the distance from a point to the end of the stippled line. Using the point's distance value, a pattern index value defines a correspondence between a point and at least one stipple pattern bit. The value of pattern bits are applied to the points on the stippled line, masking the points such that only a portion of the set of points are displayed or determining intensity values according to the position of the points within the stipple pattern. A distance function may be an edge equation associated with the line end or a segment of a polyline. The distance function can be evaluated for the set of points in any order, allowing portions of a stippled line to be drawn in parallel.

The graphics primitive is rasterized at a first level to generate a plurality of tiles of pixels. The titles are subsequently rasterized at a second level by allocating the tiles to an array of parallel second-level rasterization units to generate covered pixels. The covered pixels are then output for rendering operations in a subsequent stage of the graphics processor.

摘要： A graphics pipeline system is provided for graphics processing. Such system includes a transform module adapted for receiving vertex data. The transform module serves to transform the vertex data from a first space to a second space. Coupled to the transform module is a lighting module which is positioned on the single semiconductor platform for performing lighting operations on the vertex data received from the transform module. Also included is a rasterizer coupled to the lighting module and positioned on the single semiconductor platform for rendering the vertex data received from the lighting module. During use, an antialiasing feature is implemented to improve a quality of the graphics rendering.

摘要： Clipping techniques introduce additional vertices into existing primitives without requiring creation of new primitives. For an input triangle with one vertex on the invisible side of a clipping surface, a quadrangle can be defined. The vertices of the quadrangle are the two internal vertices of the input triangle and two clipped vertices. For determining attribute values for pixel shading, three vertices of the quadrangle are selected, and a parameter value for an attribute equation is computed using the three selected vertices. For determining pixel coverage for the quadrangle, the three edges that do not correspond to the edge created by clipping are used.

摘要： The range of depth values within the overlap of a convex polygon and a square or rectangular rasterization area can be determined by identifying whether the minimum and maximum depth values occur at the corners of the rasterization area or at intersections of the polygon's edges with the area's sides. By choosing between the corner and intersection for both the minimum and maximum depth limit, solving the depth plane equation at the chosen location, and clamping against the polygon's vertex depth range, a tight depth range describing the depth values within that overlap are obtained. That tight depth range is utilized to cull pixel values early in the pipeline, improving performance and power consumption.
