verlet with JavaScriptBuilding on top of requestAnimationFrame from earlier this week, I put together a simple example of using basic verlet integration to simulate a swinging rope in an HTML 5 canvas. You can pull the source from github, or try the sample on jsFiddle.

It’s amazing what you can do just by adding numbers together in a certain fashion. To make things interesting, there is also an option to let the rope leave a trail of pixels behind as it swings, which can make for interesting patterns (as shown in the image in this post).
