« Part 1: Dovetail Galore Part 2 of Sketchup Challenges series no next part

This has always been, and still is by far one of my favorites. so simple, yet so thought provocative:

So, as the title says – not really a challenge, but more of an inspirational piece to remind us how visual this art is, and that there’s more than one way to do anything.

I’ll let some folks enjoy the though, and will post how it’s done later on today :)

Peace!

Without knowing the answer… my thought is that the trick of this shape is in the way we assume what we cannot see. What our brain initially tells us are three pieces of square stock joined in an impossible manner into a flat triangle, is in fact a very three-dimensional object involving non-90 egree angles at the joints.

My story and I’m sticking to it. :-)

heh, I may have to hold you to that Charlie.

I’ll just say this – what you see, is exactly what’s there.

This is one of my favourite visual puzzles. So simple, and yet so very magical once you get at it just right. I do think it loses something in person, though. (For obvious reasons once you know how it is done, it’s just too easy.)

I dunno Lis. I can see your point, but I have so many of his works, and I ‘figured’ them out, but it’s so ‘magical’ (or psychedelic) to just get lost in those images and NOT try to figure it out, but just go with the flow. I am never tired of those.

Are we talking about how such a figure is drawn, or about how the figure depicted could be actually constructed?

Charlie – both.

I used to draw this design all the time when I doodle. but in this case – it’s actually constructed in SketchUp. so either way.

Ha. I have been drawing this stuff in SU all week, albeit for a different reason. With my cutting boards.
I just do it by pressing the Top view, and turning off the axes. Then draw in just 2D.
But I don’t think you did that here, as the grain follows the sticks.

But Purp, have you seen this little 3D gem? Front and Side views, followed by two off angle.

Curiosity having gotten the better of me, I looked up the answer.

I pretty much stand by my original explanation. It is a case of our mind filling in the blanks incorrectly. and angles we assume to be 90 degrees not being 90 degrees.

My only mistake was in assuming that one could play with the angles enough to actually make the ends connect.

Steve: here’s another cool one. it’s the CSUN (California State University) Sign in front of their campus. the letters CSUN can be read from both 90 degree angles – so whichever street you’re passing the campus from you’ll see ‘CSUN’:

Charlie – I told you I’ll hold you to that ;)

u got it too Ryan!

As promised, here is the “solution” which is nothing more than a view of the same geometry from a different angle:

For more similar concepts, google M.C. Escher, or just Escher. he is my favorite artist. not only does he present with a unique and beautiful art pieces, those pieces make you think, and wonder, and I’m never tired of them.

Peace.

See, now, I took it from the perspective that Escher would have used… he was an artist in a 2D medium, so I just translated that into the 2D medium of a plane in Sketchup… I suspect from the comments that shopguryl had the same approach, i.e. don’t pan around too much!

Actually, Eschers’ work although known mostly seen on canvas aka 2D medium, can be translated to a 3D medium as his work, and optical illusions ARE indeed optical illusions of 3D scenarios that seen from certain angles in 2D seem impossible.
