NewPoints will be 3D but you can ignore the zcoordinates (they should all be the same).
I've managed to plot everything again  but it doesn't look right. The shapes are preserved, but none of them are lying in just the xy axis, they've all still changed in the z direction as well. Is this perhaps because my assumption that x0 = [0 0 0] is incorrect?
