4-point perspective

I want to show a very tall tower. Actually, let’s assume its height is infinity. The thing is - I need the top to be viewed in the shot. Because I want to show that the tower is getting to the moon.
The problem , is that I can’t see the model so well in that perspective. I think the artistic solution would be to use 4-point perspective.

How can I do 4 point perspective in blender?

4-point perspective is basically the same as having large amounts of lens distortion, right? You could try a camera with a very large field of view, then use the lens distortion node with pretty high distortion value in compositor. Haven’t checked whether this gives the desired effect but I think it should work.

No, of course it’s not going work. I have tried it anyway but as I expected the result is not near what I need.

You could use false perspective to give the illusion that the tower reaches the moon by making it thinner at the top.

Use false perspective. Make the tower thinner at the top.

Use a fisheye camera in blender. That gives the right distortion

Artistic solution would be to model as it’s meant to be seen from POV.

What you’d do with a real camera is to use a bellows (“old-timey”) camera, which would allow you to adjust the film-plane separately from the lens-plane … the so-called Scheimpflug Principle. This allows you to avoid converging-lines.

(If you take a picture of a tall building with a regular box camera, or with your phone, and lay a straight-edge against the wall on a print, you’ll see that the wall appears to bend inward. The line is not perfectly straight. A bellows-camera solves the problem by realigning the film-plane.)

In Blender, you can mimic this by specifying orthographic projection for your camera. Also experiment with f-stop settings … “wide-angle vs. telephoto.”

You might find it advantageous to “comp” the tower into your shot. Compositing allows you to purposely use different camera settings for the tower vs. the background, from the same camera point-of-view. This can yield a very unsettling effect because the viewer’s eye is conditioned to expect “reality,” or at least visual consistency. The tower will look even more enormous, more of an imposition upon the scene, and it won’t be immediately obvious why.

I must admit I’ve never heard about the concept of a 4-point perspective before. Looked it up and found this.
Wouldn’t some kind of equirectangular camera produce results in this realm? What happens if you tilt such a camera (if you even can)?
