multi-touch gestural inertia experiments

dust's picture

so i have been messing with some inertia experiments as well as multi-touch gesture kind of things like apple does. i guess this one is kind of a 2-3 finger pinch scale and rotate combo. so i used some x and y speed 2 control the rotation so the velocity at which this thing rotates is entirely predicated on how fast you do the gesture plus you need to be to overlap your cursor sphere by about 1/4 to 1/2 R. so if you start outside this cursor zone and swipe in fast you will get a good rotation with some nice inertia fall off. then you can do a sort of 3 finger pinch with rotation to catch the sphere etc.. watch this quick vid of how this experiment is supposed to work. +SL source
