This is a fired 9mm bullet. You can clearly see the track of the weapon rifling on it.
This is a completely automatic scanning and calibration process done on a two-axis rotary table in a modified version of FlexScan3D.
Also you can see my new GUI for controlling the two axis turntable. It is very convenient and you can use this GUI to manually rotate the object and scan it in arbitrary positions without losing the correct position and alignment.
