FROM THE ARTIST’S STUDIO
We are at the very beginning of the sculpting stage. The CNC (Computer Numerically Controlled) foam becomes my armature for the art. Once the CNC milling comes from my vendor, we will be creating the monumental art. We got the green light from Dr. Philips, and here is how I got the files ready for our sculpting magic.
You have read below and watched the incredible video about how the 3D scanning of my small Booker T. Washington sculpture went. It was a bit complicated because we have three things with which we are working.
- The scan of the original chair.
- The scan of the small figurine.
- The scan of the small figurine taken off of the chair.
These scans were returned to me by the scanning company, and then I did several things to them. First, the 3d files from a scanning company come back to me in a format that consists of either points or triangles. I can’t sculpt on something that has triangles. There is a beautiful description of why in this Gorilla CG video. I often refer to it. If you want to know more about digital sculpting, look at the rest of Gorilla CG videos. They are very good.
Zbrush is my sculpting program. I must change those triangles into a workable quad mesh. Luckily my sculpting program does this for me. I have to find the sweet spot where I have enough geometry to work with, but not so much that it is a large file and not so little that I lose detail. Once I got that, I wanted to compare things.
I placed the total scan of the small Booker T. Washington figure and chair on top of the digital scan of the chair and watched the placement of the figure. Even after working with it for a while, I decided arranging Booker T. on the chair is something I have to see in person. Synappsys Digital services in Oklahoma will be CNC milling this for me. If we are lucky, they will be providing us with a video of the milling. They CNC in urethane foam. I hope they give me a denser foam for the chair. That way, it will be stronger. But I’ll still be making something to hold the foam in place.
We will be working on Booker T. And the chair separately. They originally wanted to carve a portion of his back into the chair. I don’t want this because it makes him fixed, and I know me. When I get him in my studio, I may want to adjust him a bit to make him look more natural.
THE FILES WERE SENT OFF, AND NOW I WAIT
When you create the files for the CNC vendor, you want to be sure the size is correct before sending it to be milled. This milling is a costly part of the process. You don’t want to have to pay to have it done again, and you can’t say, “Well, it is a bit bigger. I think I’ll just make my bronze bigger,” because that will cost money.
Keep an eye on my instagram as I can often post there what is happening faster than I can on the blog. I will be back though. Here is an instagram about the process.
