Getting started with this SLS-1 and David 3.10 software.
We are trying to get the best detail we can in a textured, sculpture object about 40mm in height, with close valleys and ridges, with up to about 3mm depth in the valleys.
I scanned from high and low angles, cleaned each of 48 scans (24 hi, 24 lo; 15 deg increments), and with WalterMo's suggested alignment/fuse technique got some pretty amazing results.
Initially I did Fusions of the fully aligned scans at 250, 500, 700, and 1000 resolution settings, with full sized scans, 50% and 25% "Reduce Mesh Density" applied, no refinement or closing. Results ranged from smooth to very detailed with some anomalies in the 1000 Resolution fusions.
File sizes of resulting obj's appears related to Resolution setting, not to the "Reduce Mesh Density" settings, that is, file sizes tended to match within 1MB no matter full size, 50% or 25% density. Based on the screen shots, the level of detail didn't seem to vary much with density, more so with fusion resolution.
So I'm wondering what the Reduce Mesh Density does, I thought it was maybe akin to jpg compression settings in 2d photography. Visually it doesn't seem to do much.
Also wondering about the language of the command, is it Reduce Mesh Density TO x% of original scan, or BY x%? Would make a difference for all but the 50% setting.
Our CAD people, who'll be working in Rhino and ZBrush to create stls for 3d printing, want smaller files while retaining sufficient detail to do what they do and I'm trying to refine the settings/workflow I should be doing. We're also all challenged by widely varying internet speeds and hardware capabilities.
Finally, am wondering about the Smooth Scans, Shrink Scan Border, and Delaunay Optimization options for the scans, what those do and in what situation to use them.
Wow that's a lot of questions! Not sure the Subject line captures it all.
