So I have a perspective question I really hope someone can help me with because I've been trying to figure this out for hours.

I have this scene in 2-point perspective, but I want to rotate an object in the scene around one of the axes (in this case, the axis going to VPR) so that vertical lines for this object are tilted. Now, I'm pretty sure this would put the object in 3-point perspective, but I don't know how find the 3rd VP for the vertical axis. If I want the new vertical line to be tilted as shown with the blue arrows, how would I figure out the VP for it?
