When to use one-point versus two-point perspective drawing?
Are there any general rules of thumb on whether to use one-point or two-point perspective?
EDIT: I should point out that I'm asking this question in the context of general art and painting.
I'm not exactly clear on your question:
If you actually mean "whether" to use one or two-point perspective, the only rule is that you should use it when it helps achieve your goals. If you're having trouble imagining the correct lines for an object in 3D space, that's when you should pull out one of the point perspective methods. Use it when it's helpful.
On the other hand, if you meant when to use one-point "vs" two-point, then that's an entirely different answer. I would say there is no reason not to use both methods in the same drawing if it helps achieve your goal. For example, two star ships may be approaching from different origins (each requiring its own one-point perspective vanishing point), from over the horizon of a post apocalyptic city (the main horizon would need its own two-point vanishing point set, while the fallen and/or falling buildings may need individual two-point perspective vanishing point sets). In fact, two-point perspective is nothing more than two one-point perspective points. You could theoretically use as many as your geometry requires. The real world is a messy mish-mash of vanishing points in all directions, so there is no reason to limit your drawing to just one type.
Good luck, and happy drawing!
