OMG Seriously, have you never heard of Escher!

OK guys, here is what I see!

I worked really hard to make that. Well, not really hard. It isn't hard to do at all but it is intentional.

Sorry guys. No I have never heard of Escher. I was trying to be honest. If I need to apologize, then that is what I am doing.

No need to apologise, just google search escher and look.
I can't imagine working in any sort of imaged based industry and not be aware of M.C.Escher.
Do the search and click the images button, then do the reading.

I looked at some of the stuff on the website but did not read at the bottom.

Got started in all of this stuff by drawing 3D car wash equipment and layouts. I am pretty naive to some of the stuff you guys share.

Scroll back up to the image Dave posted, look at the waterfall and how it drops into a 'canal' now follow the canal to see where the water goes.
Now model that path.

Dave, that is not like you. You are usually ver accurate/precise with your models.

What? This one is very precisely modeled as intended. I believe M. C. Escher would approve even if it makes Rich's eyes hurt.

mine too! so want the correction

Really nice work Dave. As far as Escher I dont know, he had his ups AND downs though

Hi! Nice work!
Can we see an orbiting animation of the model starting from the right viewpoint? It might help some to understand the trick!

Dave R

It's modeled in the same way it would need to be made in reality. Here's something to show that. Click on the image if the GIF doesn't run.

I wonder how you might achieve this. I found a quick and easy way. I've been thinking about possible ways to apply the method in a more practical sense.

psylo

Thanks !
It's great to see the method you used. I was actually thinking of a different approach, more along the lines of a perspective trick like this (not mine, found on giphy):

I think it might be challenging to achieve accurate shadows though...

Dave R

Accurate shadows would be a challenge but probably easier in mine since the straight parts aren't curved.

SHalf the woodworkers I know probably don't see anything wrong with your design.

It was okay until I sat on it! the joints were quite good, but not for 80kg
