I used Rhino. Import points -> Points to Mesh -> Render -> Save as jpeg.
This scan looks way better. Moved the camera and laser up about 3", made a new exactly cubical 1.5"x1.5"x1.5" calibration block with a gray matte material attached to the top for better visibility and regularity, and turned the lights off during the scan. I'm going to experiment with photographic filters tomorrow night to see if I can leave the lights on by filtering out all colors but laser red (650nm).
Nice job on the plugin Art. It definately has great potential!
Edit: Oh yeah, and the calibration distance was within an 1/8" this time.
