Simple deformation for projection mapping onto curved surface? jit.gl.nurbs?

I need to projection map a video on several cylindrical surfaces. I’ve made good progress with jit.gl.cornerpin to get the videos into the right place, but now need to correct for the bending. What is the best way to curve the top and bottom edges of the video? It looks like jit.gl.nurbs might work, but how do I combine it with with jit.gl.cornerpin? Ideally I’d like apply the curved correction first then send it to the cornerpin object.

I’ve seen the Manipulator patch in the Jitter Recipes – Book 2, and think I can go from there, basically using a 3×3 matrix instead of 5×5, but how do I then interpolate values across the mesh?

hello gpvillamil.
you would do something like the following patch:
