Drawing Bézier curves with JavaScript and VML (for IE only)


A progressive lesson:

Simplest case (changing the y coordinate of one endpoint)

Generalization (identifying the two end points)

Adding behavior (an earthworm in a cyclone)

Grouping things and moving them together as a group

Attaching two bézier curves together, smoothly (let them share a point, and let the adjacent control points be collinear with the shared point)


Fancier things:

Eeliness (letting points on the curve follow one another, sort of)

a bézier drawing tool -- 

a simpler version  (my kids like it better)

and a bézier tree


A sampling of VML
