thanks alot dear.....
but my project is augmented virtual reality in which i will have
graphical 3D hand on the screen and i will capture movement of my real hand
on cams and then when i move my real hand so graphical hand will move
according to the movement of my hand...so now what you will suggest which
library to use....
thanks....
