Title: Animation using Harmonograph equations Post by: Haversine on February 13, 2015, 03:02:22 PM The parametric equations modeling a Harmonograph were used to make this animation. Youtube takes a few seconds to switch to 720p HD, so the animation does not look very good for the first few seconds.

I refined the animation a little bit and added a parametric index into a color map to provide color.
Youtube compression really takes a toll on the image.

Title: Re: Animation using Harmonograph equations Post by: Haversine on February 15, 2015, 10:14:38 PM The harmonograph equations I'm using contain four different sinwaves (two for each axis) with damping. The "art" is defining a trajectory in the sinwave parameter space to follow during the animation timeline. This is not just a Lissajous pattern if that is what you mean by "normal sinwave animation".
