I'm going to ask a really stupid question about perspective here. I've read various tutorials and done perspective drawings before, but I am still a bit confused so I thought I would turn to you guys for help so I can finally lay this to rest...
Do all Vanishing Points end on the Horizon Line? Generally I would say, yes. But then when it comes to 3 point perspective, it will not be on the H.L.
Is there a specific way that you can determine the height of the 3rd V.P.? Or is it just something that you eye-ball. I've been eye-balling so far, but feel that this may not be the right way to do it.
Also, is it possible to have an large amount of V.P.'s in the same picture? Just for every set of parallel lines you need another V.P., right? So if you are drawing, say, a messy room with boxes at various angles, will they all have very different V.P.'s if none of them are parallel?
Hope that people can answer this so I can finally stop questioning these things!
