Having a series of micro-CT images from soil/rock samples, what is the most powerful tool to convert it to 3D model (STL file). I already know about ImageJ, but due to the high quality and resolution of the images I was not able to use ImageJ.
I use MIMICS software -pricey , but in my opinion the best out there, especially for CT imaging. I have used it on several micro-CT data sets with no pre-processing or advanced work even when the data sets are huge. I have had some where the micro-CT data was broken into two or three sets by the scanner and was able to build each independently and then assemble into a single file at the end.
When data sets are huge, you could break them into separate stacks using the software and then assemble them at the end. What constitutes a HUGE data set depends on the machine you are using and the configuration.
If you're wanting to do segmentation and meshing, the linked paper provides an overview including a table with 8 possible software options. Of these, SPIERS is free (http://spiers-software.org/). Not included in that table is 3D slicer (https://www.slicer.org/). If you have a budget, Mimics (as mentioned above), or Avizo are standard.
We provide software that can load micro-CT images and perform isosurfacing to extract a surface and then export that surface as an STL model. If the model is too large we can work with you to figure out a way to extract the surface. Our software is much more affordable then MIMICS and other tools.
It's been a long time since you've asked this question, but for your future works, I offer you the BN Co., I think, with their own software, they can do it in a best way: www.BehinNegareh.com
You can use Dragonfly to segment and export to STL.
It provide powerful deep learning segmentation algorithm and It is free for non-commercial use. Go here to download https://www.theobjects.com/dragonfly/get-trial-version-request.php
