EXTENDING DX11 GPU FOR PROGRAMMABLE VECTOR GRAPHICS

摘要

The present disclosure provides for path rendering including receiving, with a graphics processing unit (GPU), data indicative of a path segment of a path to be rendered. The systems and methods render the path segment by performing a fill of the path segment, which includes tessellating the path segment into a first plurality of primitives including a triangle per primitive, storing a first plurality of primitives in a stencil buffer, and drawing a bounding box of the path segment and rendering the bounding box with a stencil test enabled. The systems and methods also stroke the path segment, including tessellating the path into a second plurality of primitives, re-tessellating the second plurality of primitives, cutting the second plurality of primitives according to a dash pattern, creating a cap at a location of a cut, and creating a triangulation of a stroke and rasterizing the stroke based on the triangulation.
