quadraped walk cycle demo


Untitled from coop on Vimeo.

As promised, and because I'm becoming less convinced of my ability to give a lecture AND critique 25 students in 3 hours, I'm going to attempt to post more additional content on this blog.

Really, this is nothing terribly fancy...a 25 minute demo of how to rough in a quadraped walk cycle with a few bullet points and no audio. The technique was shown to me by a pretty spectacular animator, Jan VanBuyten who has done animation from Balto to The Host - he really knows his creatures, and this is my take on his methodology of roughing in the basic mechanics. It's a much more layered approach than I generally take, but it takes you pretty far into the cycle quickly, while keeping it editable.

Let me know if this is useful..it's my first attempt at making something using screen capture software-the whole thing is realtime with no editing, so you can see me make some wrong moves and backtrack a bit in places. Also, it's playing at double speed, recorded at 15fps, so you never see the final cycle in real time...(more detailed info to come)

Hey Jeff, just wanted to chime in. As a former student of yours, I think this demo was really helpful! I wish we had more of this when I was in your class last semester. Thanks!

Thank you so much for posting this video tutorial. I always wanted to know how to approach a 4 legged walk.

One question. What was the tool you pulled up to ghost the geometry?

jeff said...

the ghosting tool is phantomWindow.mel written by jeremy cantor at www.zayatz.com

i have a bunch of my most used mels up at http://coopdesign.org/aac/aacScripts.zip including a tweaked version of his copyTransf.mel, which is very useful..demo to come on that shortly

Bear in mind, this is just one method into a quad walk and should be just used as a method - i've known other animators that just do the front legs and then back legs and get good results that way, for example.

jeff said...
