Designing with Euler's Elastica
This script takes a cubic Bézier curves and projects it to a cubic Bézier curve that is close to an elastic curve.
For details see our article: Bezier curves that are close to elastica.
Only the two interior control points can be moved. Hit reload to reset. A blue Bézier curve means a "good" curve (contained in the projection zone), where a red curve means a "bad" curve.
