Export of subdivided mesh

[kvanhoey]

Hello,

I tried exporting the meshes after subdivision using the binary command-line flag (last option). This does create a new mesh whose content is erroneous.

Example for a subdivided quad:
Input quad.obj

v -0.500000 -0.500000 0.500000
v 0.500000 -0.500000 0.500000
v 0.500000 0.500000 0.500000
v -0.500000 0.500000 0.500000
f 1 2 3 4

Output quad_1_SLAK.obj

v 0 0 0
v 0 0 0
v 0 0 0
v 0 0 0
v 0 0 0
v 0 0 0
f 1 1 1 1
f 1 1 1 1
f 1 1 1 1
f 1 1 1 1

I suppose this is a bug in your code. Can it be fixed?

Regards,

Kenneth

Hi! Glad it compiles now. Would you mind sending me the actual command line you used. I'll check what's going on as soon as I can. Are you on windows or linux? Best, Daniel

Thank you for the quick reply.

Command-line:
./SLAK quad.obj 1 1 1
where quad.obj's content is given in my initial post.

I'm on Linux Ubuntu 20.04.

Huh, okay. So it works fine for me here on windows, but there might have been a problem with the different line endings in windows/linux. I pushed a potential fix into the dev branch, but I could not test it properly yet, as I do not have a working linux distribution here right now. Feel free to checkout if what's in the dev branch works for you now. Best, Daniel

Just tested it. To be sure: - I checked out the dev branch - compiled - ran the same command as above. For the same result, unfortunately. The file structure looks OK: there are the right number of vertices/faces, but not the right values of vertex id's and vertex geometry. So I doubt it's about line endings ...

I'll check when I'm back at my linux workstation. On Wed, Sep 30, 2020, 18:57 Kenneth Vanhoey <notifications@github.com> wrote:
