Now the I finally had some spare income, I decided to purchase a 3d Printer! I purchased the Photon S on amazon during a promotion Amazon was having and I can only saw WOW. I love the fine quality of detail this printer can produce. While it can get a bit smelly at times, this printer has the ability to keep very fine details of a model, provided they have the proper supports built in. In thew coming weeks, I hope to have a new post added that showed the process that shows what I had to go through to attain the model below.
This is the finished sculpt that was imported into Houdini to be used in my thesis, before adding my procedural rock texturingÂ
Now that I had the head mesh it was time to sculpt.. this is the raw mesh data the was imported into Z brush
My girlfriend Jenna volunteered ...(volentold) to be my test subject for this attempt.
I took 4 sets of photos for this try
1 under her chin
1 angled upward from her chinÂ
1 directly at her face
1 above looking down
In photo-scan these were the settings I used
I am in no means an expert but these setting seems to work fine for me and did not take days to compute

With 100 Percent Honesty, this blog is being written about a year after I have created the 3D scan, I'll try my best to remember everything as it was and some of this is gonna be copied and pasted from my MFA thesis paper. :)
I did several different experiments to see what would be the best result for scanning a head. At first I bough a computer screen Lazy Susan and had the subject stand on it. I added a green screen behind them and rotated the subject 10 degrees for each photo, taking photos at various heights. Then keyed out the green screen and used that key as a mask, to be imported as a separate file into PhotoScan.
While this works......it takes a while to edit the photos. So instead I decided to build a rig that took up the entirely of my living room to rotate around my subject removing the need for a green screen.
Going to youtube I viewed a few tutorials as to how to create a 360 camera rig.Â
