[MORPHMET] Re: NextEngine Laser Scanner

2017-11-11 Thread terrielsimmons
Hi Callie, 

Are you using the old NextEngine or the Ultra? Since you are scanning at a 
small distance, make sure your scan setting is set to macro. Try fewer 
divisions, around 8--too many divisions for small objects causes the 
auto-alignment to not work. The NextEngine also has a hard time aligning 
flat objects, so if the scans don't align within ScanStudio, you might have 
to export them to Meshlab and align them. You can email me directly if you 
want some help with Meshlab.

[MORPHMET] Re: Looking for software to place landmarks on 3d data

2017-05-09 Thread terrielsimmons
Hi Grace,

You can use 3D Slicer or Meshlab to place points on 3D models--both are 
free.

[MORPHMET] Re: MeshLab - setting default FOV as Ortho?

2017-01-20 Thread terrielsimmons
Hi Christy,

I don't think there's a way to set Ortho as the default view. I just change 
it with Windows --> View from... Meshlab 2016 has more options under this 
menu, for example, to select front with the z up, like CT scans. You can 
also hold shift and scroll the mouse wheel.
