You might think this is a fact when you talk to many artists. Why can’t a painting idea be created in three dimensional space? Why do you have to take six-point perspective back to the flat surface? What if the idea works best in three dimensions?
Just because we would like all things to fit in books doesn’t mean all things have to. You know, we live in a three dimensional world, not the two dimension of the book. I think also many artists wanted to be able to reproduce their ideas for more sales and it is much harder to reproduce in the third dimension. That, maybe could have a lot to do with how they wanted their images to turn out.
When I was at Otis Art Institute in Los Angels I was ask by one of my fellow students, when was I going to “Get serious and get back to the Flat Surface”. I am pretty glad I didn’t get serious.
