In this paper, we present a novel path rendering scheme that provides a fast rendering on high resolution mobile device. Because legacy path renderings are memory intensive work, they do not provide enough performance (fps) on high resolution display. To get an acceptable performance, we propose a novel approach for path rendering. Our design policies for the path rendering are two folds: 1) Minimize memory I/O, 2) Highly parallel computational scheme. We propose to use winding number generator for per-pixel winding number calculation which does not require memory intensive activity. Because our scheme effectively reduces memory I/O and it is executed with highly parallel manner, we can get an acceptable high performance on high resolution mobile device.
