The finite precision of floating point computations can lead the coarse renderer into inconsistent tile intersections, which implies impossible line segments such as lines with gaps or double intersections. The winding number algorithm is sensitive to these errors which show up as incorrectly filled paths. This change forces all intersections to be consistent. First, the floating point top edge intersection test is removed; top edge intersections are completely determined by left edge intersections. Then, left edge intersections are inserted from the tile with the last top edge intersection. The next top edge is then fixed to be the last tile with a left edge intersection. More details in the patch comments. Fixes #23 Signed-off-by: Elias Naur <mail@eliasnaur.com> |
