Re: [MORPHMET] Importing .scn files into Geomagic Design

2018-03-05 Thread Thomas O'Mahoney
Dear Kai There was a plug-in a while ago for geomagic that could do this. Unfortunately since acquisition by 3D systems, finding these old plugins is very tricky-it may be available with careful searching and possibly using the way back machine on internet archive (if they captured this part of

Dear Miguel, This was discussed a few months ago. The popular models at the moment are the LMI HDi series and the Artec Spider and Eva series. All start at around $15k, depending on what you buy. All give very good data and all have very well written software, much of which can also be scripted

Dera Luci and Angela Roggero, Nikon and Northstar imaging are also manufacturers that are worth looking into. The Nikon XTH225 is extremely popular in the UK for digitising objects from ~2cm up to ~50cm. Resolution varies between 3-5 microns and 100 microns, depending on sample size etc. If you

2016-12-06 Thread Thomas O'Mahoney
Dear Lawrence, Stefan Schlager's excellent Morpho package for R has the option to slide semilandmarks without the mesh. I have had some success with this myself, but you can of course include your mesh with these protocols in either Morpho or Geomorph (written by Dean Adams et al.). Best, Tom On

Hi all, Both the R packages 'Morpho' and 'Geomorph' will allow you to estimate missing landmarks using either thin plate splines or regression. It's about 3 lines of code, fully explained in each package, to import your data and then estimate the missing data. Both packages accept a variety of

Re: [MORPHMET] How to export .obj with textures as .ply with colours for morphometric analyses?

2016-09-07 Thread Thomas O'Mahoney
Dear Viviana, I had this problem recently. I seem to remember that it was solved by saving the files with no spaces in the names. so instead of, for example "skull 2.obj", save as "skull2.obj" This will help the textures associate properly. Then when you've converted to .ply, it doesn't matter,

Hi, This subject pops up every few months on Morphmet. The general consensus is that either Creaform or structured light scanners like Artec or LMI have made are generally very satisfactory solutions. People like Breuckmann are an order of magnitude more expensive but also very good. You'll want

Both Artec scanners and LMI's HDI series scanners are more than good enough for scanning materials for morphometrics. I have used both on several projects, and know lots of groups with either that are happy with their choice. As Dennis says, the LMI series works very well with a turntable. You can

Hi John, Yes, I have a lot of experience with the Hdi scanners, both the fixed calibration and adjustable ones. They are great for archaeological material/bones (I've literally scanned thousands, as have my colleagues at Cambridge, Bradford and TBI in Kenya) and I've had good success with

Dear Andy, Having used the NextEngine with both the minimum and recommended specs (for scanning humeri)I would advise to go for the recommended specs as a baseline. As you said RAM isn't a problem,I'd put as much as you can in (although to go above 4gb you'll obviously need a 64bit OS) -the
