According to the OBJ spec linked on the main page, comment lines should be ignored, but they aren't. Instead, the program just bombs:

[FATAL] line:4 Unsupported line "#98 vertices, 124 faces"

Please submit a bug report. If you can, provide this file as an attachement.

Hi there;

I'm a non-go user and struggling to actually build/run the program. I realize it's likely user error but including a note may save many hours for folks like me :) Would it be possible to include instructions to get going for people like me who havn't ever touched go? ie)

git clone <repo>
cd obj-simplify
go build

This actually fails as-is with "cannot find package "github.com/jonnenauha/obj-simplify/objectfile", running in the golang official Docker container, so I assume that's a functional go build environment.

hi @jonnenauha! first of all, thanks for this tool. looks great and fast.

I encountered an issue with this tool throwing fatal error

[FATAL] line:381459 Found invalid number from "-1.#IND00 -1.#IND00 -1.#IND00": strconv.ParseFloat: parsing "-1.#IND00": invalid syntax

when trying to simplify the object. note that I am not very knowledgeable about the .obj format or any other 3d format. I bought model of my Mazda6 and got obj file with lines like:

vt  0.673680 0.303679 0.000000
vt  1.000000 0.303948 0.000000
vt  0.250000 0.661712 0.000000
vt  0.250000 0.161712 0.000000
vt  -1.#IND00 -1.#IND00 -1.#IND00
vt  0.205604 0.321078 0.000000
vt  0.794396 0.321078 0.000000
vt  0.481795 0.692745 0.000000
vt  0.329577 0.631309 0.000000

so I am not sure if there's a problem with obj-simplify tool or with my .obj file.
Also, note that this file can be opened with the online 3dviewer or tools like blender.
I would appreciate any help on this one, thanks!

This is a neat tool, you earned my star! However, it seems that any faces with over 4 vertices are truncated to just the first 4 vertices when exporting, which is kind of inconvenient since I have models with octagonal faces.

It seems like the upper index limit here could simply be removed to fix the issue, although I'm not super familiar with the code base or the language.

or put differently, will this run ever complete or is it too big? :) 30k scene objects in Blender.. (from a FBX)

Does anyone know what the issue is?

I know it's a very large file but that's why i'm using the program

When trying to simplify a file, I get this error after RAM usage goes up to 34GB using amd64 version on Windows (tried with windows 10 and windows server 2012).

runtime: out of memory: cannot allocate 2359296-byte block (34358820864 in use)
fatal error: out of memory

It crashes way faster when using 386 version.
Is this a RAM problem ? I have 64GB.
