Bezier clipping against all orthogonal axis

July 17th, 2005

After I trying some studies with my AS1 solution I found a lot of misbehavior, while clipping. So I started to develope a completely new solution in AS2. The code provides to clip against any orthogonal axis and furthermore it's easy to extend in 3D. The hardest issue was to solve a division by zero in a few cases. I've tested it for a long time and it seems to be solid for me. Anyway, if you found any bug, please leave a comment.


drag the anchors and watch the results. the bezier is clipped against the darken area.

    Unfortunately I found some rare cases where the clipping fails. I have tested the single axis for a while, but not the simultaneous clipping against a rectangle (4axis).
    In some cases a bezier curve with no dimension can be returned and forces the further computation to fail.

    No time for fixing this right now, but I will. I’m also ambitious to see a possible 3D experiment.

    Worked well for me, thanks for making this.
