From Art Geek:
Following on my previous post, I decided to actually carry out a painting based on the last SketchUp prototype. Here is the procedure I used this time:
By the way, I adopted this from a technique described by Gregory Gillespie in the early 1990s when he was a visiting artist at the University of Wisconsin — Madison, and have developed it for my own work for quite some time. The procedure takes some practice to get right, but there are many variants, each of which is suitable for a different texture, level of accuracy, speed, etc. For more variants of the technique, see “Hollis Brown Thornton”:http://www.hollisbrownthornton.com/'s writeup.
When the transfer is done, you can then start painting. Acrylics work well at this point, or you can go straight in with oil (but then, no acrylics on top of the oil, or your painting can develop adhesion issues down the road). I use and absolutely adore water-soluble oils, so these days I typically go straight to those. My studio is 99.9% free of organic solvents (I still use a tiny bit of cobalt drier from time to time, which has a bit of solvent in it).
I doubt I would be able to develop this kind of imaginary mechanical structure in correct perspective without the aid of SketchUp or other 3D modeling software.
The current state is shown here. I expect more color to develop and possibly even radical changes down the road:
Parenthetically, it is exceptionally rare that I get to apply 3D vector mathematics and programming (for the SketchUp plugin) and painting in the same project. Ironic, too, that though I work in physics, I am using all that juicy math for art, rather than for physics!
