Four Point Perspective Grid by JohnColburn Four Point Perspective Grid by JohnColburn
This is some graph paper I designed to help with drawing four-point perspective. Four point is the one where lots of lines are curved and it warps the picture so you can see (for example) an entire room at once. This grid is specially adapted for drawing the interior of just such a room with the addition of bold outlines for the walls and extra vertical lines across the "surface" of said walls. The walls are twenty grids wide and ten grids tall, making for a medium/large room if you assume the lines are one foot apart (20x20 foot floor space with 10 foot high cieling...). Obviously you can see one full wall and two half walls per page, so it would take two pages to draw an entire room.

This image is the same size as american letter paper in landscape (11 inches by 8.5 inches) at 600dpi and is suitable for printing. If you want to print it, make sure you download the full size AND tell your software to print without scaling (maybe tell it to "Crop" or "Preserve Dimensions").

If you're not sure how to use this grid, try looking around online a little bit; there are a few tutorials around. Here's a quick one I found on deviantart which isn't very detailed, but does a great job of demonstrating the general idea. I'll probably post some of what I'm drawing on these grids tonight/tomorrow/soonish, so that might also help.

No problem. I hope it helps you out ^^.

This is very cool!

Strictly speaking, I do believe this is a three-point perspective, since you're only showing three vanishing points. (It would be four if you had four horizon VPs, as in the tutorial you link to, or if you added an 'up' or 'bottom' vanishing point.) Though, I know that when one says 'three point perspective' everyone assumes it's two on the horizon and one up or down.

This grid is only half of a "complete" four-point perspective grid so that it can be printed on american letter-size paper. You'll need two sheets to do a full panorama, if that's what you need.

Making it narrower doesn't make it three-point; three-point perspective is a completely different technique. You could call this grid "partial four-point perspective" or something, but the use of straight vertical lines with curved horizontal lines identifies it as some sort of four-point setup.

In any case, I'm glad you like it ^^.

Yes, fair enough. I hadn't realized the terminology had standardized that way. Now I know!

When I wrote to you, I was midway through my own perspective investigations, which resulted in this guide [link] to where to put vanishing points on the horizon.

I had this idea that a certain distance (in pixels) away from the center of the image corresponded to a fixed change in viewing angle, but that turns out to be completely wrong.

Thanks a lot, I'll try to experiment with these.
Simple curiosity, but how did you create the lines? They look like they're the result of some mathematical formula, and I'll have to admit playing with perspective is something I enjoy, so...

There was no fancy equation behind these lines. I used the program Inkscape to draw a circle, then made many copies of that circle getting squashed flat toward the center. Made two "clones" of the set, one to either side. I picked a size that looked about right for the back wall (no math, just eyeballed it) and made that shape by tracing the existing circles, then cloned that as well. Then I went through all of the circles and tweaked them until they intersected the tops and bottoms of the walls about 0.25 inches apart, which I got by dividing the width of a single wall by 20. Similarly, for circles entirely inside the back wall I just adjusted them so that they divided the walls into ten even sections. For the vertical guides, I just went across and drew straight lines from top to bottom connecting the intersections from the circles.

If it sounds like a lot of work, it really wasn't. The real trick is cloning the circles so that you only have to adjust the middle set and the circles to the sides will match it. Then if you know what you're aligning them to (the top and bottom of the wall, in my case) it's pretty simple to go through the circles from smallest to biggest, putting each one where it goes until it's done. What's harder is deciding on what measurement you really want; I made some versions with different numbers of circles, different sized walls, and so on before I decided I liked this one.

Huh, sounds like an interesting trick if one can manage it.
