Here is a combination of several projects in one. I started with my recent experiments with 3D laser scanning, and the portable rig I built. (Based on a design from the David 3D scanner web site.)
For more detailed picture of the setup and assembly see my YouTube video.
I was inspired to take a scan of my face and morph it into a Moai after seeing some of the Moai Madness going on in the lab (over at Open3DP).
Here is the initial scan of my face:
AccuTrans 3D to re-orient and scale (stretch lengthwise) gives this result:
MeshLab was then used to clean the edges:
Then back to AccuTrans 3D to extrude:
Back to MeshLab to smooth (Laplacian Smooth, several times in different areas until it looked nice and even):
Finally some "mesh aging and chipping" in MeshLab:
Here is a 3D print of the final model:
