Abstract: This disclosure is directed to techniques for performing GPU-accelerated path rendering. A GPU is described that is configured to receive data indicative of a path segment of a path to be rendered, tessellate the path segment into a plurality of primitives, and render at least one of a fill area and a stroke area for the path segment based on the plurality of primitives. The techniques of this disclosure may be used to improve the performance of path rendering operations, to reduce memory bandwidth requirements needed to perform path rendering operations, and/or to reduce the memory footprint needed to perform path rendering operations.

Abstract: A tessellation unit of a graphics processing unit (GPU) determines domain coordinates for vertices of a received primitive. The tessellation unit outputs the determined domain coordinates for the vertices. The tessellation unit further determines that a domain type for the received primitive is not one of tri, isoline, or quad domain, and outputs information indicative of a graphical feature associated with one or more of the determined domain coordinates when the domain type is not one of the tri, isoline, or quad domain.
