Re: [MORPHMET] Help with surface scans

2019-05-08 Thread G Wrobe
Pablo — I use photogrammetry to create models from skulls and I’d be happy to 
share my workflow if you want to experiment with it.  It works really well in 
most cases. I’ve been curious about about the Spider scanner, so would love to 
hear about your experiences with that.  Feel free to drop me a line at 
wrob...@msu.edu .

Dear Ariadne

Thank you so much for your kind response and excuse my delayed reply. I´m
using an Artec Space Spide scanner. I´m doing some tests following several
of the guidelines here suggested. For lithic tools some reflecting surfaces
typical of some raw materials like chert produce some errors but is just a
matter of test. Thanks again for your advice.

All best,

Pablo
