Stacked and rotated boxes
A cube, a rotated cube, a slab and a tall block: four boxes, three sets of vanishing points.

What to look at
The rotated boxes have their own vanishing points on the same horizon: rotation slides the points along it.
A box on a box shares the lower box's top plane; its base ellipse of contact is a rectangle in perspective.
Tall block vs slab: the same edges, different proportions, same rules.
