摘要： A method and system for selective enablement of tile compression. The method includes receiving a graphics primitive for processing in a set-up unit of a graphics processor and determining a primitive characteristic that indicates a probability of whether a final compression of a tile related to the primitive will be retained. Compression for the tile related to the primitive is allowed when the characteristic indicates the final compression will be retained. Compression for the tile related to the primitive is disallowed in the characteristic indicates the final compression will not be retained.

摘要： One embodiment of the present invention sets forth a technique for rendering graphics primitives in parallel while maintaining the API primitive ordering. Multiple, independent geometry units perform geometry processing concurrently on different graphics primitives. A primitive distribution scheme delivers primitives concurrently to multiple rasterizers at rates of multiple primitives per clock while maintaining the primitive ordering for each pixel. The multiple, independent rasterizer units perform rasterization concurrently on one or more graphics primitives, enabling the rendering of multiple primitives per system clock.

摘要： The current invention involves new systems and methods for providing variable rasterization performance suited to the size and shape of the primitives being rendered. Portions of pixel tiles that are fully covered by a graphics primitive are encoded and processed by the system as rectangles, rather than expanding to explicit samples. This accelerates the rendering of large primitives without increasing the computation resources used for rasterization. In some embodiments, these fully-covered regions can be rendered compressed without ever expanding into samples.

摘要： A method for multiple queue output buffering in a raster stage of a graphics processor. 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 to generate a plurality of tiles of pixels related to the graphics primitive. Each tile is then rasterized to determine related sub-portions of each tile. The related sub-portions are transferred to a plurality of output queues. The related sub-portions are subsequently output on a per queue basis and on a per clock cycle basis.

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.

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： A method and system for smooth rasterization of graphics primitives. The method includes receiving a graphics primitive for rasterization in a raster stage of a processor, rasterizing the graphics primitive by generating a plurality of fragments related to the graphics primitive, and determining a coverage value for each of the plurality of fragments. If one edge of the graphics primitive lies within a predetermined inter-pixel distance from a pixel center, the one edge is used to calculate the coverage value by using a distance to the pixel center. If two edges of the graphics primitive lie within the predetermined inter-pixel distance from the pixel center, a distance to the pixel center of each edge is used individually to calculate the coverage value. The resulting coverage values for the plurality of fragments are output to a subsequent stage of the processor for rendering.
