Simple Equipment
A crappy Xbox Live Vision camera will do the trick, especially if you don't need crazy resolution. (The free version of the software doesn't do hi-res anyway.)
In the Corner
The pattern on the back of the 90 degree intersection helps in calibrating the camera.
The Setup
A good stand is important. The darker and thinner the less it shows up on the scan. One out of two isn't bad.
Tool of Destruction
A cheap ($20) laser leveler, normally used to hang pictures straight, used as a line laser. Not the greatest quality but you can't beat the price.
Scanning the Mask
The actual scan is done in monochrome with far higher contrast.
Scans side by side
The six scans arranged side by side before aligning.
Aligned Meshes
The six meshes have been aligned
Fused Meshes
The six separate meshes have been fused into one.
The Man Himself
So to speak...
