Segmentation fault when calling `bin/PreprocessMesh`

See original GitHub issue

Hi,

after following the build instructions of https://github.com/facebookresearch/DeepSDF/issues/81#issuecomment-953495747 I get a segmentation fault when I try to run

bin/PreprocessMesh -m in.obj -o out.npz

Is this a known issue? Are there any current workarounds?

Thanks

Here’s what I did to build the program and all dependencies. You need to be root for some of these commands to work. Also, this will not work if you’re running the program in a remote SSH session, you need to have a screen (I tried some workarounds but I couldn’t get it to work).

Anyway, I suggest you not spend too much time trying to make this code work. There’s a much better python library called mesh-to-sdf (https://pypi.org/project/mesh-to-sdf/) that does the same thing without any of the hassle. Just pip install mesh-to-sdf and you’re good to go. Still won’t work in a remote session unfortunately, but it’s also way faster than the code in this repo.

Here’s the full list of commands (disclaimer: don’t just copy-paste the whole thing, make sure that every command executes successfully):

apt install git cmake build-essential libglfw3-dev libgles2-mesa-dev libgtest-dev libeigen3-dev
