Hello,

I just try to learn a little the volume meshes and I think that VolumeMesher is a great work.

What can be the recommended viewer for the produced volume meshes? For example, how to view the tet file? With Medit? Medit seems quite old. The gl.h used is not compatible with the one on my Windows .

Hi, thank you for your interest in our work! I am not aware of any public code to directly visualize these files, but their syntax is rather trivial. Both TET and MSH formats are basically a "volumetric" version of OFF files for polygonal meshes. I believe you can easily implement a converter to any standard format supported by your favourite viewer. Hope it helps.

Hello MarcoAttene,

Thank you for your help. I'll try to view the generated tet file with libigl, referring the libigl OFF reader.

Info:

I tried to use gmesh to open the output file of VolumeMesher, "volume.msh", obviously it is not compatible. The output msh file from TetWild has no problem with gmesh.

As I said, I am not aware of any public suitable viewer. Though the files produced by VolumeMesher are similar in spirit to the format in OFF files, they are not OFF files. You may not be able to use an OFF reader to visualize them. I believe you definitely need to implement your own parser if you wish to convert these files to another format. Possibly in the future I will provide such a converter as part of this repository, but I have no time for that now.

Regarding the MSH format - This is just an unfortunate choice of the extension, which is the same used in gmsh, but it's not the same format actually.
