I’m working through the 250 box challenge and having difficulty foreshortening my boxes in various ways. Should each of the three sets of converging lines be angled to a nearer vanishing point or only one plane?
One thing to keep in mind is that there are two things that will change the rate of convergence of an object's lines.
There's its orientation - as the form rotates, some of its sets of parallel edges shift more towards running parallel to the viewer's angle of sight, so those vanishing point slides closer to the center of the picture frame, and some of its sets of parallel edges rotate more towards running perpendicular to that angle of sight, so their vanishing points slide further and further away until they reach infinity.
And there's the overall rate of foreshortening, which applies to all of these sets of edges equally.
If you're trying to shift the overall foreshortening, you'll be bringing all the vanishing points closer, or pushing them all further away. If you're only doing it to one or two sets of parallel edges, you'll be rotating the form instead.
Thanks for the reply, very helpful and a lot to process!
These are what I use when doing these exercises. They usually run somewhere in the middle of the price/quality range, and are often sold in sets of different line weights - remember that for the Drawabox lessons, we only really use the 0.5s, so try and find sets that sell only one size.
Alternatively, if at all possible, going to an art supply store and buying the pens in person is often better because they'll generally sell them individually and allow you to test them out before you buy (to weed out any duds).
