Vector art sway in breeze
Posted by Michael Becke on November 13, 2006 at 5:24 pmHi,
I’ve got an illustrator graphic. (some curly vines and straighter ones)
I wanted to get the feeling that they were being affected by a light breeze… gently swaying.Anyone got any advice for the most realistic solution?
Any advice welcome.
Cheers,

November 13, 2006 at 6:32 pmI’d suggest you look at Displacement Maps, to take the mystery out of Displacement Maps, click on Aharon’s Head above and scroll down (lots of tuts = lots of scrolling) to:
Displacement Mapping Part 1: The Basics
Displacement Mapping Part 2: Avoiding the Pitfalls
Maybe an animated Displacement Map alone will do the trick, but here is an earlier post by a previous AE Leader Rick Gerard that makes Illustrator Files into Wheat Dancing in the Wind:

He uses the wiggler to animate the Max Horizontal Displacement and Max Vertical Displacement Stopwatches, but you can use this wiggle expression to do the same thing:
wiggle (5,30)
This seems a little to much for gently swaying vines (but the technique is killer, IMHO) so you’d need to tweak to taste.

November 13, 2006 at 6:35 pmMost realistic: Separate all elements in Ilustrator, paste the paths as curves in AE, then animate mask shape. Intermediate realism: Separate the shapes and give each of them some Turbulent Dispalce with different settings. No realism: Don’t separate, just use one or two instances of Turbulent Displace on the entire layer.

November 13, 2006 at 7:31 pmJust remember that your displacement map is a greyscale value, where grey would be a zero value, not white (which i believe would be a negative value.) So if you want the attachment point of your vines not to move, the displace map should be grey.
I’m also thinking, if you use fractal noise to make the displacement map, you could keyframe the transform>offset Turbulence, which would shift the noise say left to right, might be a bit more realistic. Pretty sure you’ll need to precompose that layer as well.

November 14, 2006 at 11:53 amThanks for all the answers, YikeSmikes – that tutorial was very useful, thanks!
Mylenium – I totally agree that the most realistic would be to animate the masks individually especially since some vines have curles on them… so if I have enough time I’ll try that.
Eric – Interesting point with the noise… I’ll try add that to the tutorial Yikes added.
Jason – I’ll give it a try and see if I can get it looking any good
Thanks all again

November 14, 2006 at 1:40 pmIf you are experienced in expressions theres a tutorial by Dan Ebberts about the expression Noise
I haven’t tried apply it to anything but in the tutorial he states it’s great for “Natural effects like wind flowing through a field of grass or lilypads on a pond.” It sounds like it might be perfect.
