Save tetgenpy output to file?

[Florian-Konrad]

Hi :)
I generated a tetrahedral mesh like this

tetgenout = tetgenpy.tetrahedralize("", plc.to_tetgenio())

now i'm wondering what a good way is to save the mesh in tetgenout to file?
Cheers

Hi Florian,

if you are familiar with / your pipline uses tetgen native formats, you could use TetgenIO.save_*() functions. You can load those using TetgenIO.load_*() functions

Otherwise I can imagine a simple numpy based io:

np.save("tetgen_io.npz", points=tetgenout.points() , ...)

Best,
Jae

Thankfully, vedo started to natively support TetgenIO objects - see #9. For example:

import vedo
...
tet = vedo.TetMesh(tetgenout)
tet.write("out.vtk")

Hi Jae,
thanks for the info! Vedo looks awesome!
I had solved it with building a meshio object from the tetgenout myself and exporting to exodus format.
But cool that vedo can probably do this now, too!
