is an open source software program used to manipulate and edit mesh data. This tutorial will specifically show how to assemble, clean and reconstruct data from a 3D laser scanner. The techniques used with the scanner used here should apply to scan data from any machine, but first read any documentation included with your system before beginning.
One must use their judgement when scanning the object to be sure to capture enough data to create the best mesh possible. The alligator head used here required around 30 scans taken from various angles. Typical scan sets may be as small as 5 and as large as 50. This was a high number due to all of the hidden geometry inside the mouth. For scans taken with a calibrated rotary turntable, the coarse alignment steps may be skipped entirely. However, it is still recommended to do a fine alignment to eliminate any error inherent to the turntable. As with any software, backup your work and save frequently.
