This is very Escher-like. I've never seen a nice explanation of this before:

I have never seen anything like that before. Thank you for sharing.

Cool! I've tried them all except the 5th and 6th one. =3

this is new to me too. thanks Ernest

Hi,
6 point perspective is a very interesting topic Ernest. I had some trouble getting my head around this. So I took your lead and looked for some more info. The best short tutorial that I found that helped was here. Now that I get it, do I really want to draw it? I think it would be a nice technique to try on the view of the Alps from my home. There is actually a web cam on the roof of the university in front of our home. We're just above it so I pretty much have the same view. I always wanted to draw this but could never get it all in. Now I know why.

Sounds like a project! Thanks for the tip.

Wow, RJ -- that sounds spectacular. I would love to see you do that!

that's amazing! I never thought of trying so many points!

Very interesting, yet too advanced for me.Ernest and RJ thanks for the links.

Not to plug someone else's book, but this one's helping me a lot on perspective. While it doesn't cover six-point, it explains, very well, 1-5 point and even infinite-point perspective.

Fooling around, I doodled these little buildings in (what I flatter myself to call) four-point perspective.

This has come out great. I think this process would lend itself very well to cartoons. I will be giving this a try. Thanks Ernest

That's great Ernest, it must be dificult to do!!!

Lance I would love to see how that comes out in cartoons.

3D exploration of Picasso's Guernica.
Guernica is a painting by Pablo Picasso, depicting the Nazi German bombing of Guernica in Spain by twenty-four bombers, on April 26, 1937 during the Spanish Civil War, in which a number of people variously estimated between 250 and 1,600 were killed and many more were injured.

German artist Lena Gieseke made an 3D exploration of Picasso's Guernica. I think this tip for review fits best in this thread.

Thank you very much for his beautiful link on perspective. It is a precious enrichment for my students and forum.
