Dynamic Response for Motion Capture Animation

Zordan, V. B., Majkowska, A., Chiu, B., Fast, M.

Human motion capture embeds rich detail and style which is difficult to generate with competing animation synthesis technologies. However, such recorded data requires principled means for creating responses in unpredicted situations, for example those immediately following impact. This paper introduces a novel technique for incorporating unexpected impacts into a motion capture-driven animation system through the combination of a physical simulation which responds to contact forces and a specialized search routine which determines the best plausible reentry into motion library playback following the impact. Our system generates a physics-based response as it transitions between motion capture segments using an actuated dynamic model and smoothly moves the character toward the re-entry clip over time. Our method allows characters to have un-canned responses to unexpected changes in the environment based on the specific dynamic effects of a given contact while also taking advantage of the realistic movement made available through motion capture. We show the results of our system under various conditions and with varying responses using martial arts motion capture as a testbed.

How old is this?

[aigamedev]

Research from 2004, presentation in 2005 I think...

Bet the guy at 2:35 was going " Ow! Dude, what the hell?"

The guy that kicked him: "sorry..."

[MicrosoftsourceCode]

is this using the Dynamic Animation and Control Environment software?

[NewAgeDirector]

Great video keep up the good work.

Never heard of natural motion? It's a software company that makes more realistic rag doll engines, Google natural motion euphoria.

What program is this? motion builder?

[TheGothicwear]

Fine egsample...

[Gconstant10]

I am interested in dynamic response for a project. How can I contact you?

[WeretFilms]

What software are you/people in this video using?

[TheFXGuy]

just use endorphin... lol

[amig90]

Very nice. I would much prefer to have this in a game if I'm using mo-cap. I think a similar technique was used in GTA 4 where characters reacted to impact in a less rag-doll fashion.

Is that for games or special some other special programs?
