bind grid to object?
I basically want to bind my grid to a real life object – in this case a square made of cloth. I want to be able to turn it (with a push pin in its middle so it stays put), the grid imitating the direction it rotates. the idea was to use it as a volume knob in an installation.
I’m rather new to jitter & apparently haven’t come up with the right key words yet (for this issue must have been marked off quite some times) – the search function didn’t bring me luck this time..
thankful for any point in the right direction..!
all the best

thanks for the quick reply, EMV!
the only cv.jit from pelletier’s library that suits my intention would be the cv.jit.features object (..my thesis as a noob). all I’d have to do is feed cv.jit.features with exactly (!) 4 points: all 4 vertices of my predefined square.
but how can I prevent cv.jit.features from letting my hand interfere with the feature’s initial coordinates? it’d be a disaster if my fingers would relocate single features.. (thus destroying my square)
I’m still stuck on this, studying the cv.jit library as suggested..
it’s not the movement of my hands I want to capture, merely the movement of a single square.
anyone know how to make my (jit.lcd) frame imitate its movements (respectively getting data from a 2-d real life object with non-varying proportions)?
all the best..!
