compositing a hand
i have a model of a ring and i have some video footage of me acting as if a ring is moving in the air slowly towards me and i end up catching the ring but
the ring is 3d so for me to actually grab the ring i have to model my hand right..? and match move th3 3d hand to my hand
now here is my question how can i set up maya so i can track the 3d hand with my hand...!!
coz i was thinking if i just use a plane and try and track that, when i go to composite it all together the 3d hand could be out of proportion
i hope its not to confusing for u lot... if it is ill put up some images
of what i mean..
thanks in advance..

This process is called roto-mation:
Key the movement of your hand object frame, by frame, to match your 2d video plate.
Just one idea....

The only times you really NEED to track in a 3D stand-in for your hand are:
1) When you want to render 3D shadows cast by the ring on your hand (you can often get away with cheap 2D tricks in this regard but you'll need to do SOMETHING in this area to make the composite work.)
2) When you want to simulate dynamics that are affected by the shape of your hand, like moving it through smoke or having something travel along its surface.
3) When the animation is so complex that you really need to have accurate reference for where the body part is. Example: the spyders in Minority Report crawling on Tom Cruise's head required doing 3D roto (the term for matching 3D animated stand-in geometry to photographed objects like Tom's head) so that their contact points would be accurate AND for shadows.

u cud try using maya live or any other method (like the one rage mentioned first), then render the animation with an alpha channel, in a compositor, use the alpha to remove the 3d hand from the ring plate so your real hand shows through with the 3d ring
