Perspective Question

[Grifter730]

I'm trying to learn perspective, so I got a question here. On this particular image (it's a scan of a comic), obviously the vanishing point is down at the bottom of the page somewhere. My question is, is this a one-point perspective, or is it possible that it could be more than one? Take the sidewalk for example, will it actually end somewhere, or is it just going to be parallel the whole time? I'm just wondering if it's even possible that this shot could be done in 2-pt perspective. Here's the image:

I am not the master of perspective here or anything but that is 3 point perspective.

The cars/sidewalk and everything going that way heads down one vanishing point.

everything that is at a more or less 90 degree angle to that the cracks in the sidewalk some of the stairs (anything heading off to the distance to the left) is heading down to another vanishing point.

Then the height of the buildings themselves and any vertical lines head to another vanishing point.

I am sure someone can come up with a diagram, or correct me if I am wrong.

Not 1 pt.
Not 2 pt.

3 pt!

Three point perpective is what you get from a bird's-eye or worm's-eye view. There are no non-converging lines because nothing is parallel with the picture plane. It is, needless to say, the most difficult perpective scheme to construct. I'd say the example you posted was almost certainly done straight from a reference shot.

yeah, they are right, it is 3 point perspective.
but you can have 1 point, 2 point, and 3 point perspective all in the same image. When you get the vanishing points set, you are establishing where parallel lines converge. If you draw two buildings in one image they don't have to be drawn from the same vanishing point unless you want them to be parallel to each other. If one building is turned then it will have a different set of vanishing points. One example of different vanishing points is an open door, the door part doesn't go to the same vanishing points as the door frame. The vanishing point will be located on the same horizon plane though, because the door and the door frame sit pretty much on the same "floor" so to speak. I hope that makes sense, if not maybe someone who understands it better can explain.

So are you saying an image like the one I posted can be drawn in 1pt perspective? Like, an overhead from the sky shot like that, that can be drawn in 1pt?

[Elwell]

If you are looking straight down, and everything is either parallel or perpendicular to the picture plane, yes. As soon as your viewing angle becomes the least bit tilted, however, you're dealing with three point.

Ok, first let me establish that, this image is 3 point, and everything in it conforms to those vanishing points.
What I'm saying is in that image, you could have an object that is in 1-point perspective in there. I'll have to get the bookI read on this stuff and post some diagrams. I think it's more of perspective book for architecture. Which means its more mathematical(don't worry no equations to deal with though) so it goes into depth a little more.

Does 1, 2, 3 etc point perspective mean, how many Points of view there are?

[Elwell]

Not quite. One of the basic conventions of linear perspective is that there is only one, fixed point of view. The "points" in 1pt, 2pt, 3pt refer to the number of vanishing points an object has, which depends on its orientation relative to the viewer.

Check out the perpective threads in the Middle Class for more info.

i just have to add a bit to elwells first post:

a) 3 point isnt the most difficult perspective setup, 5 point curvilinear is. :)

b) i dont think this panel is complicated enough that it needed a reference shot. could be that there is ref stuff used, but... nah, it isnt really difficult stuff in there... only 90 degree angles and some stairs.
