is there a way to deal with numerous scanned data to mesh a model in a similar way to mashlabs or pointclick?
can you give a little more detail on what “deal with” means?
decimation, alignment, triangulation, rendering, export?
when we do a scan, it has multipe single files, these need to align and mesh with options to adjust the quality of finish - detail, hole filling and smoothness. it would be fantastic if this is something Rhino can do
Typically this is done in a scanner specific app, such as Artec Studio.
Some aligning can be done in Rhino but it’s a rather manual task. Once everything is aligned, you can shrinkwrap multiple meshes.
How many individual scans do you have?
Typically 12 or 24 or 36
12 per scan, then you might then rotate the item being scanned then re scan etc. 3 lots of scans is normal
What scanner do you use?
You could do alignment in Cloud Compare with the ICP fine registration tool.
However, it only works on two scans at a time, and it will not globally optimize the scan registration on the entire group of scans after you have completed aligning pairs of scans. Globally optimizing the entire group of scans is necessary to distribute the error between any two scans over the group. You will most likely need a paid tool for that if the results of pair alignment are insufficient to produce a good overall registration.
Meshing options are limited in Cloud Compare, but you could use another app for that.
You could also look at Reality Capture to do alignment and meshing (free if you earn less than 1 million $), although I have had mixed results with it.

Thunk do have their own mesh software but a new model from Ukraine is being launched and this needs a 3rd party software and that’s where this solution request has come from
I think it is more efficient to do this in an as native solution as possible than trying to piece things together in Rhino.
I appreciate the comprehensive response, thank you

I didn’t see that these are scans form a hand held scanner before I completed my response.
You will need specialized software for this as Martin indicated. There is no “free” software to work with these kinds of scanners. If the scanner maker is not offering a bundle with software, check to see if the scanner is compatible with Geomagic or PolyWorks. These are very costly apps but there is no way around it.

its looking like this, thanks. Pointkit want $50 pm which is bonkers
