Hi, I made some changes to the file reader, can you run the latest code and tell me if it works for you?

Now I get

melkor:/melkor/d1/guenther/projects/threejs/OBJ2GLTF> node bin/obj2gltf.js ../obj/test5.obj ../obj/test5.gltf

buffer.js:803
  this.parent.writeFloatLE(value, this.offset + offset, !!noAssert);
              ^

I've tried a different OBJ file and found this:

/melkor/d1/guenther/projects/threejs/OBJ2GLTF/node_modules/gltf-pipeline/lib/findAccessorMinMax.js:17
    var min = new Array(numberOfComponents).fill(Number.POSITIVE_INFINITY);
                                            ^

I'll past the OBJ file here so you can try it out yourself:

mtllib /melkor/d1/guenther/projects/threejs/obj/test3.mtl

v 10 10 10
v 20 20 20
v 0 0 0 
v 0 -51.2692 269.668

g grp1
usemtl mtl1
l 1 2 3 4 
f 1
f 2
f 3
f 4

[hamogu]

Thank you so much for your quick responses!

[lilleyse]

For the example you posted we don't support line segments like l 1 2 3 4 right now. Rearranging your example a bit works, but it may not be exactly what you want:

mtllib /melkor/d1/guenther/projects/threejs/obj/test3.mtl

v 10 10 10
v 20 20 20
v 0 0 0 
v 0 -51.2692 269.668

g grp1
usemtl mtl1
f 1 2 3 4

Can you also send over your other obj?

/melkor/d1/guenther/projects/threejs/OBJ2GLTF/node_modules/gltf-pipeline/lib/findAccessorMinMax.js:17
var min = new Array(numberOfComponents).fill(Number.POSITIVE_INFINITY);
^
TypeError: Object has no method 'fill'

What version of Node do you have installed? Updating may fix that problem.

[hamogu]

The other file is a lot bigger (> 15 MB), and it also contains line line segments, so that's probably a related error.
I'm visualizing a ray-trace simulation for a scientific instrument and rays are lines, so I cannot really do without lines. I'll try to work directly with the OBJ format for now, but I'll keep your converter in mind and come back to it later if I have the opportunity!

melkor:/melkor/d1/guenther/projects/threejs/OBJ2GLTF> node --version
v0.10.42
(I'm using CentOS and that's the version I get through my package manager.)

[lilleyse]

Ok, thanks for all the info. Adding support for line segments shouldn't be too bad and I'll update this issue when it's ready.

@lilleyse hi，i got the same error. i tried to read a file like xx.html.
here is my code

[lilleyse]

obj2gltf isn't using the readline package anymore, you should investigate with them instead. You could also check out the byline package which seems to be very solid so far.
