recently I met this problem, and I dont know which pd object has this function which is shown in the attachment pic,
and this is a vvvv snapshot, the vvvv node (like pd object) named homography
Its function is to control the vertex of the rectangle to fit the real wall which is being projected in any possible angle.
so my question is the is there any object to control the gem rectangle or any 3d model's vertex in pd ?
thanx a lot!
