ABSTRACT:
Systems and methods for identifying pixels that are inside a two-dimensional path may be used to fill the path. The path is segmented and a point in space is identified that is used to generate a triangle fan, where each triangle in the fan is formed by one of the segments of the path and the point. Locations in a winding buffer are updated for each pixel that is within a triangle of the triangle fan. The resulting winding buffer indicates the pixels that are inside the two-dimensional path. The winding buffer may be used to fill the path.
