As an assignment for a series of tutorials on perspective I've been going through, I am trying to construct a general approximation of the building shown below as part of a "wild west" scene. I already started constructing it and know how to create the "slice" in the corner of the building, which is outlined in red.
However, I am unsure where the VP(s) would be for the objects coming "out" of the slice or that are perpendicular to it, such as the planks of wood in that area. I would think that they would have a unique VP (s) from those that the two sets of blue lines recede two, which are your standard left and right vanishing points.
I'm wondering if any of you guys can advise me on how to construct these objects that are perpendicular to the slanted "slice" of the building. Thanks so much for your help.
By the way, I do not by any means claim this photo to be my own. I am simply using it as reference.
