'extract mesh' outputs a 'strange' mesh

[hg111]

hello @SuLvXiangXin ,

I was trying out the nerf_llff_data/room dataset. Rendering looks good, and so I gathered training went well, and the extract command had no apparent errors with either extract.py or tsdf.py mesh, however in both cases it outputs a 'strange' mesh when I preview the output .ply file. I also tested pymeshlab and it seems to work fine on it's own (converting for example from obj to ply). In all cases I used default values.

What am I missing?

Below a screenshot of the ply shows the conference room table and chairs in an "incomplete scene"
