Re: Ref: Free laser scanner software

I too have been trying it out.

I now have a good camera, laser setup, with a reasonably high res
webcam and a choice of red or green laser lines, and can get good
scans from test objects.

but I want to scan chromed and polished items..

To get round the surface problem I have been experimenting with white
powder paint and dishwashing liquid as a whitewash..
So far so good.. it makes a very reflective, or transparent object
scan-able, and washes off easily in water.

I have used Meshcam to generate the toolpaths.

Its going to be useful, but I haven't used it in anger yet !
