I have a plug-in that offers functionality similar to Photoshop’s perspective correction tool (as mentioned in this thread: How to distort group of curves as in photoshop command?).
The plugin still needs refinement, could definitely use some beta testing, and destined to remain free of charge throughout. I’m willing to attach it here if that is acceptable to McNeel/Forum. Or to some other, more appropriate spot.
Here is a demo of how it would work with this particular setup (I apologize for the low level on audio):
Not necessarily an easy process, but not too bad either.
