 advice/ tutorials on animating a bird images wings? on Jul 13, 2010 at 12:46:31 pm

My next task will involve animating the wings using information from a still image. In other words, I have a still image of a robin and I want to make its wings move realistically (or as real as possible). Tutorials/ instructions regarding this would be appreciated. Thanks, Jon

Is this an American Red-Breasted Robin or a European "robin"? Their wing rythms and flight patterns are quite different.

American Robin

American Robin. Thanks

I can't contribute any information regarding the authenticity of the wing flap of an American Robin, however there are several tutorials on-line about animating butterfly wings.

The method requires a minimum of 3 parts for the animation: body, left and right wing.

Make all 3 layers 3D.

Move the anchor points of each wing to the appropriate edge.

Animate a single wing's Y Rotation with the following expression: 60*Math.sin(10*time)

The numbers refer to amplitude (60) or the height of travel of the wing, the other number is the frequency of the wing flap.

Use the pickwhip to tie the Y Rotation of the other wing to the Y Rotation of the animated wing and add a minus sign in front of the expression so it reads something like this:

-thisComp.layer("right wing.psd").rotationY

Now parent both wings to the body and you're done.

To control the wing flap you can use expression sliders for amplitude and frequency rather than hard coded numbers.

I usually cut up the birds wings in 2/3 sectionsand parent them together.
Then animate rotation by hand.
Wasn't going for realism though.

I hope you're up on your 3D work! Here are some slo-mo examples:

You will note that in REALISTIC flight, bird wings have thickness, change their shape and move throughout all three dimensions.

American Robins tend to fly rather low to the ground (probably because they're so fat [that's not an Americans Are Fat joke, American Robins just look fat...okay, it's sort of an Americans Are Fat joke.])
Anyway...low to the ground and in bursts of flapping. Fluttery-fluttery-fluttery- short glide, fluttery-fluttery-fluttery- short glide, fluttery-fluttery-fluttery- short glide, etc.

Good observation, Michael. But I think both our posts are pretty fruitless.

This guy wants wants realistic flying... but he wants to apply it to a STILL IMAGE, for heaven's sake. Yeah, that'll look realistic, all right.

I'd like to get from Buffalo, NY to Albuquerque, NM in a minute-forty. Like this guy, I think I'm out of luck.

Well that's ridiculous. It's a simple question of weight ratios! A five ounce bird could not carry a one pound coconut. A European Robin maybe, but of course European Robins are non-migratory :)

Well, if European Robins won't carry it because they're non-migratory, suppose two American Robins carried it together? American Robins migrate.
