When I need a Homography Adjustment, I usually make an IObox (Value Advanced), like the one with Original Points in the Homography help patch, for each adjustment I need to make. I do this to achieve more precise control by holding down shift and ctrl keys while right dragging.
I am currently making a new installation where people, not familiar with vvvv, will need to do homography adjustment of some projectors.
I would like to make a more friendly adjustment patch that work via network.
So this is a quick post before I begin making my own such patch to see if anyone of you have already made such an adjustment patch that you would be willing to share.
