Leaving painted graphics on stage is very powerfull to create nice images with simple movement algorithms. Related to this study a few years ago, I’ve recreated it with the new BitmapData possebilities.
This AS2 code provides clipping against any orthogonal axis. Furthermore, it’s easy to extend in 3D.
This SWF computes the rectangular bounding (aabb) of a quadric beziercurve. This is usefull to pretest object intersections in e.g. physics engines.
A curtain created by particles connected by bezier curves.
A balls collides with a quadric bezier spline.
A ball follows the path of a quadric bezier curve.
Split a quadric bezier curve by two parameters [t0,t1].
