Hello everyone. I wanted to know if a 5mw green laser and a webcam Logitech HD C270 can start testing this wonderful software.

This is my result with a logitech c160 to 640x400 30fps.It is a plastic figure, do I have to paint it off-white?.

Hi
Yes, it is always used. scattering of laser light in matt white surface.

Sometimes, if the plastic surface is glossy, it's hard to scan such an object. Then it's necessary to coat it. But don't paint it if the color is also glossy. Have a look to this thread where we have collected some different ways of coating:

WalterMo, thanks for everything, I will continue testing.One more query, what minimum for a good result is 800 x 600 30fps, I mean the laser scanning.

Yes, 800 x 600 is a good resolution. We should take into account that a complete scan of an object sometimes needs circa 20-50 single scans. So after alignment the complete 3D file can easily grow up to values which are over the limit of our computer's possibility. Best is to use a 64 Bit operating system with sufficient memory (8 GByte RAM).

Fortunately, in the meantime, DAVID has become a 64 Bit software. :D

A tip for a cheap and simple "motor scanner":

In general it's better to sweep the laser line 1x very slowly over the object than multiple times very fast.

Finally, the structured light system also must prepare plastic parts for scanning.

Thank you all for the help.
