@bjudeworley can you take a look at this? Thanks!

I'll try and take a look but I now have a 3 month old so my free time is basically nil so it might be a while.

If I had to guess, the 0.17.0 output probably has one of the bad element types my PR aimed to fix, or requires generating them at some intermediate step in the decimation process. Maybe take a look at the output mesh in something like Meshmixer and see if that's the case.

@limpbot, your example doesnt have enough info, what is the value of mesh_vertices_count?

from open3d.

hi @bjude, thx for taking a look. The vertices count should be 7055, and the faces count should be 15670.

@limpbot can you re-upload the mesh, its 404'ing when i try and download it

from open3d.

Sorry, I have also problems loading it currently. Will reopen if I find another example
