I've been a way from Vuo for a minute but have returned in an attempt to make a quick FFGL plugin for Resolume. The goal is to augment the keystone, or four-point transform tool, to include points midway between each corner. This allows for a very quick 'Z-perspective' transform, pushing or pulling the centre of the image from the viewer.
I can't figure out the best way to go about this, whether I should be sending the input imagine to the surface of a cube that is rotated 45º (y axis), or to a mesh object with these extra points, that can then be adjusted on the x & y coordinates.
Any thoughts would be super helpful. I feel like this should be a fairly straight forward tool but I can't wrap my head around which node to focus on.
