[MORPHMET] Re: scaling conundrum with 3D models
Many thanks for the reply. I have been using the professional version and also the scale bars made by CHI. The models are scaled in Agisoft. I just confirmed that ply files should maintain scale. So, perhaps I am just doing something wrong in Agisoft. But, good to know about this workaround. gabe On Friday, November 9, 2018 at 3:07:24 PM UTC-5, Katrien Janin wrote: > > Hi Gabriel, > > You will indeed need to set a scale to your models, as this is lost when > you create models with Agisoft.

Hi Gabriel, You will indeed need to set a scale to your models, as this is lost when you create models with Agisoft. If you have the professional version, I believe you can do this within Agisoft. If you, like me, have the standard version, you can use meshlab (freeware) to achieve this. Here is a handy video whihc explains you how to do this within Meshlabs : https://www.youtube.com/watch?v=6psAppbOOXM I hope this helps, Katrien G.

[MORPHMET] scaling conundrum with 3D models
I have built scaled photogrammetric models of crania with Agisoft, which I want to use for GM analysis. But when I open these in Stratovan Checkpoint and begin placing landmark points, the scale is wrong -- length measurements on the models are around half what they should be. I suspect the problem is that I am not exporting the model in a format that maintains the scale (I have been using ply files). Any suggestions about what to do about this? Ideally, I'd like to create a model that opens in Checkpoint correctly scaled and in color. My ply files do the latter.
