Hi, can someone help me identify this 3d format. Its ascii from a webgl.
Thanks

I don't understand what you need to identify. It's ASCII. You just read it off.
Since you know it's webgl you just need to get a copy of webgl and pass in the data.

Yeah this is actually the easiest one ever

mqo based data

if you open it in notepad++ and put some carrage returns in it you get this:

Code: Select all

var m = {
	"colors":[],
	"edges":[],
	"faces":[[43,21,5,41,...,3051,2677,2677]],
	"materials":
	[
	{
		...
		"mapDiffuse":"\u5e8a.bmp.jpg",
		...
	}
	]
	"normals":[[0.6124,-0.2346,-0.7548,...,0.7993]],
	"scale":100.0,
	"uvs":[[[0.0,0.0,0.8333,0.4285,...,0.7751,0.4182,0.8073]]],
	"version":2,
	"vertices":[[1.5155,88.8848,...,-0.0377,85.8348]]};

I removed most of the data just to pin point the relevant data

I was wondering and interested in what kind of a model this was....

but then I took a look at the faces list...

and after a few entries I got a question

43,21,5, 41,57,2, 0,0,0, 0,0,1, 1,0

how can you have a face ( triangle) that is indexed 0,0,0 ???

also, the number of faces in the list is not a multiple if 3 ...

The faces are not just vertex indices. If you were to say it is mqo-based, the face stores UV indexes and material index as well. And other info. It would be easiest to just download the parser FROM the website where he got the model from and then just copy the methods.

Here's what we got before without bothering to look at source code.

Though, at this point, I think if people REALLY want the models, they might as well just grab the source code and send the output to an OBJ exporter or something.

However the script is minimized so figuring out what's going on might be a little tricky.

Oh, it also supports animation. webgl is quite amazing.

It's kind of interesting how fast javascript could load that thing. I tried parsing it in python and it just took forever. Or maybe cause I was converting everything to bytes...

Thanks anyways

Thank you for the help. This is the script that loads the model.
Anyone know how i can execute it and convert the model from js to mqo?
