Hey guys,

 

i'm trying to anmate G2 turning 90 degrees while staxding. i'm in a wheelchair, so i can't really do the motion to figure oiut the process myself.

 

What moves first? The hip 9r the foot going backward?

    I would say the hip would lead with the foot lifting and the leg swinging around to follow the hip direction soon after hip movement starts. It will be interesting to see what other ideas people offer about this.

    If you are doing a whole-body, usually the head starts turning first, so you can see where you are going. After that, it can vary, depending on age and training; dancers and martial artists move differently to, say, a footballer, and men and women turn differently to each other. Weight height, and pregnancy all affect how an individual moves.

    I believe there are real-life motion captures that illustrate this sort of thing. It may be worth your searching for them.

    And, just to fine tune this, the eyes start to move just before the head.

    Ah, cool. Then, from kamae-te (ready stance) you snap-turn the head at the same time you step back with the right foot into kiba-dache (horse stance), and start your arms going to uchi-uki, or shuto-uke, depending on the defense you need. (Heh, I taught traditional Shotokan style for over twenty years, but retired now)

    Never mind that I'm in a wheelchair. I teach Isshinryu Karate as Nidan.Been studying different styles since 2007.

     

    Meh, getting into horse stance without slippy foot in 3D animkation is not easy. This one was way easier. had to redo it though.

     The fact is that we don't think about it, we just do it. Like putting words together. the process of thinking, moving the tongue, pusing air through the vocal chords, etc are all sort of automatic. So it's hard to say "here's how I move".  But one guy (Dean Kamen, I think is his name) actually put a lot of thought into that question. He one summarized the art of walking as actually shifing your weight to make yourself fall, then stepping into it to stop the fall.  He was an expert on gyroscopes which sort of do this too. Using this sort of thinking he built things like the Segway scooters and wheel chairs that could climb stairs. Smart dude. Interesting observation on human motion. 

    So using that line of thought, in turning I'd think the hip starts to rotate (i.e. the weight begins to redistribute) and the feet follow to maintain stability.  I actually tested it and just slowly did a turn without thinking about it. , my hip starts to rotate and then I swing my opposite leg (i.e I'm rotating to the right, my left leg) swings forward and plants to keep me upright. As I continue to rotate, my other leg is now positioned poorly and automatically takes a step backwards and plants. And with those two steps, I'm facing the opposite direction.

    Would McCasual's script help with slipping feet? I don't do much animation but the scripts of his I use are really useful.

    This is exactly why I teach karateka not to practice sloppy technique. The more you do something, the less you think about it.

    Good info. Thanks

    Well, I'm using Carrara, which has target helpers I can setup to nail theb foot to the floor. It's just that I'm trying to pivot around the toes -- or should it be the heel? Let me go spin someone until they're dizzy. lol And then it gets all wacky nd i have to put it all in thes right spot
