Hi everyone, I am quite new to 3D slicer and haven’t figured out many of the function yet. I found this blog post on volumetric mesh support and I would like to experiment with its capabilities. Can someone might give me an explanation on how I get such a volumentric mesh? I always end up with an…

There are several extensions that advertise the capability of generating a volume mesh, but I don’t know whether they are functional and/or maintained. https://www.slicer.org/wiki/Documentation/Nightly/Extensions/CleaverExtension https://www.slicer.org/wiki/Documentation/Nightly/Extensions/PBNRR T…

Hi Julian, I thought I would share my experience that I have had lately with volumetric meshing and include the problems I am having I tried using cleaver with limited success. I had a lot of trouble with the extension initially. After I spoke with Andras Lasso I was able to get the meshing worki…

[image] Michael_Hardisty: the mesh did not contain tetrahedra as far as I could tell. Instead it contained 4 triangles representing the faces instead of tetrahedra. Have you tried the new Cleaver library? Does it still write volumetric meshes like this? [image] Michael_Hardisty: the mes…

Thanks for follow up. This enhancement should be helpful to our group.

Dear Michael, Can you please post the screen shots of how you successfully got the tetrahedral mesh for geometry of interest. Does it produces cube always even if the segmented label is provided and you want tetrahedral mesh for only that portion of image? Regards, Saima

Hi Saima, I looked back at my notes and I don’t have any screenshots. We’ve moved in a different direction on this project. The vtk based method is essentially possible with code snippet in the thread. Are you referring to one of the other methods I had tried? Which method are you referring to? …

Dear Michael, Thank you for your reply. The problem is to get the volumetric mesh of brain from the cubic mesh generated through using segment mesher. The brain is inside the cube. How do I achieve this? How did you use the threshold to cut the unwanted regions of mesh based on intensity values? …

@Michael_Hardisty I’ve added Segment Mesher extension that can generate volumetric meshes using Cleaver2 or Tetgen. See a bit more details in this topic: Convert 3D slicer into 3D solid body
