Horizontal lines you draw on the faces of cubes, granted that you wish them to appear parallel to the horizontal edges should be treated the same way as the edges. The lines to the left of the forefront vertical edge should point to the left vanishing point, the right ones to the right vanishing point. The exact angles are to be determined by the distance between the two points and the placement of the cube between them. If you're looking for an equation to calculate this before putting pencil to paper, you ought to ask a nerdier board.

It's art related though

Is this bait? I hope so.

I-I don't get it

All parallel lines vanish to the same vanishing point. If the lines on your cube are parallel with the edges on your cube, they will vanish to your two VPs. If they're vertical (as in 2pt perspective has not vertical VP) then they don't vanish at all. Anything else vanishes to an inclined VP.

This has all the answers about perspective, period

It's Loomis son Jonathan Loomis who unfortunately died young in a tragic auto accident. The still image is from a rare vhs copy of a lecture he held at art center in the 80's just weeks before the accident. A young Craig Mullins can be seen in the audience taking notes
