CONVERSION OF DASHED STROKES INTO QUADRATIC BÈZIER SEGMENT SEQUENCE0

One embodiment of the present invention sets forth a technique for converting dashed strokes into quadratic Bèzier segment sequences. Path rendering with stroking and dashing may be accelerated when a graphics processing unit or other processor is configured to subdivide quadratic Bèzier segments based on the remaining distance for a current dash pattern element and the arc length of the current quadratic Bèzier path segment to generate “on” dash pattern segments. Each “on” dash pattern segment is then bounded by a conservative geometric hull. A point containment technique is then used to identify pixels within each conservative geometric hull that are within half of the stroke width of any point along a path to be stroked.
