Removing hand movements while keeping slow light traces in live projection.

Feb 16 2011 | 2:27 pm

Hi, I’m doing fine art project and new to Max and jitter.
I’d like to create an installation of dust in light – projected slow motion live on a wall.
I want people to move their hands through the light/dust beam leaving light traces.
However on theI’d like to remove the hand itself so that only the moving light traces are projected on the wall when people make their movements.
Any help gratefully received.

My first thought is to model the dust in a 3D enviroment and track the hand by motion tracking. Next use the movement data to adjust the dust parameters in this enviroment. I think that’s more easy than substracting hands from a random (dust) enviroment
