3-D Sidewalk Painting

Found this on Fark... pretty wild stuff!

Link














These two show a good perspective of the same painting at different angles:

wonder if they are as cool live or if it is just a photo "trick",.. i know it's not a trick, but maybe the camera aids in the illusion

not a photo trick. Google on Trompe L'Oeil.

Very spiffy. It would be neat to see those in person.

I saw one (in Las Vegas maybe?) and it was really impressive.

It's not a photo trick, however, as the globe one illustrates, you only can really see what the picture is from that one position where the camera is placed.

Those are stinkin' awesome!

I wish we had shots of them all from other angles... expecially an "opposite" view. I'd be interested to see how that looks.

If you were at an exact opposite view, I think you would get an illusion of them being "concave" instead of convex. Which could look pretty trippy with some of these. I could be wrong though.

Good stuff. Not particularly amazing, but some good art. The "trick" is that the angle of observation (in this case the photograph) must exactly match the perspective of the drawing or it doesn't work. The inclusion of a living human helps. But, note also that most of the pictures are in a "low light" situation, which helps the trompe l'oeil effect because it removes all the external cues so that you *must* rely on the perspective cues in the drawing itself.

But I bet they look normal if you're travelling at twice the speed of light!

You must be a lot of fun at parties.

Not the most convincing, but the best theme. Pretty good stuff. Does he just do it on the fly or repeatedly check his view when drawing, or have a camera set up to draw the perspective?

you can say it only looks right from 1 perspective, but the guy on the left definitely looks like he is trying not to fall in a hole:

Think he's just trying to not step on the painting.

I mean, with both eyes, you must see that the guy is actually there, while the painting is flat on the floor, not?
