View Full Version : 3 Point Perspective Question

I am working through perspective drawing, and came to some confusion after a bit of drawing.

I realize that in three-point perspective, you set an additional vanishing point for the vertical lines, but how do you draw multiple objects without them being disoriented from each other; that is, tilted in different directions so that they do not appear as if they are resting on the same surface.

For example, take this drawing (an example of mine); does it look correct in terms of my question?

Bump.

Has my question not been answered because it was posed in a confusing manner? I'd really like some thoughts on this..

I believe all of the towers would still have the same vertical VP.

Thanks John.

I am trying this out now in some sketches and it is simply not working.

Also, I can't view the link you posted as it requires me to sign in.

Something you need to consider for the vertical perspective is the shot that you're attempting to paint/design. For example, in the picture you gave there would be very little visible vertical perspective because the viewpoint is only at a slight angle higher than looking along, or parallel, to the horizon. The shots where vertical perspective is apparent is when looking upwards at a steep angle, say 60 degrees from the horizon upwards.

There are situations where you'd put the 3rd point in with slighter angles, especially if you're looking 'down' on a scene aswell, but the point still remains that if the field of view is only at a slight angle parallel to the horizon there won't be much vertical perspective. That's why your image looks odd because you're artificially 'injecting' vertical perspective into a shot that naturally wouldn't have a great deal.

This was really a test; I am still learning how to properly set up my scene, and I thought I'd ask get some help.

I have enclosed an image which shows my setup for this sketch; I'd appreciate your comments (or anyone else's for that matter.)

Thanks, I'll have to take a look at that.

All objects in view will have the same vertical VP, not separate ones, so if anything they'll lean 'towards' each other rather than away. If you don't use it in the right context though it can produce warped geometry that will look as though it's being viewed through a circular reflection - it's all about field of vision.

When you look up at an angle that emphasizes a three-point perspective you'll generally only see large objects like skyscrappers or objects suspended in air as everything else will be out of your field of vision. Those large objects will mostly dominate the view so fitting 3 large structures in a three-point perspective piece may give a warped look. In other words significant vertical VP is usually only seen from viewpoints that contain one maybe two large structures, anything more than that and you'd need to be at a distance where the vertical VP becomes fairly insignificant.

Try to focus on making a vertical VP for a single skyscrapper where the viewpoint is based close to the base of said skyscrapper, then branch out to adding more buildings and placing the viewpoint further away from those structures.

After I read this over a few times, I finally got it.
Here's a new 3-point drawing (http://img443.imageshack.us/img443/7335/3point3.png) that I did yesterday - let me know what you think.

Cheers! :)

I believe this would be considered 2-point, since all the horizontal lines are parallel.

Yeah, you're right. :p

I found some good info.

1 point (http://www.khulsey.com/perspective_basics.html)

2 point (http://www.khulsey.com/perspective_2pt.html)

3 point (http://www.khulsey.com/3_point_perspective.html)

Enjoy!
