Animate <feTurbulence> SVG filter

Recommended Posts



I'd like to animate an SVG <feTurbulence> filter, where I can animate the `baseFrequency` and `numOctaves` values down to 0. 


How do I select these values to animate them in GSAP, and is this possible?


Codepen link attached, but I guess on a theoretical level it will either be something like this:


Pseudo Code

Tweenmax.to (feTurbulence, 1, {numOctaves: 0, baseFrequency: 0})


Or would I do it something like this:


Pseudo Code

TweenMax.to([numOctaves, baseFrequency], 1, {opacity: 0})


And of course once I know which of the two theoretical ways is correct, how would I select with the turbulence filter itself or its attributes. I've traditionally only used GSAP on DOM or SVG elements and not filters or filter attributes so this is a tad confusing.

Many thanks in advance for any assistance.

You'll just need to use the AttrPlugin. Please give this a try:


TweenMax.to("feTurbulence", 1, { attr: { numOctaves: 0, baseFrequency: 0 } });

Happy tweening.

Thanks @PointC 

I deleted my initial reply because I see it is part of TweenMax (it was a question about how to add it to codepen because it's not on the list of plugins you can try on codepen).

Yep, the AttrPlugin is automatically loaded with TweenMax.

Happy tweening.




PS Check out this demo too. It shows what's loaded via TweenMax and has CDN links for the Club plugins for use on CodePen.
