It looks like the best way to go is going to be to use a native JSON format file.
Essentially this means that I don't have to write a mesh parser at all, which is nice.
To get to JSON I was originally looking at using a Python script to convert .obj to .json but it looks like there is...
...an exporter for Blender3D
called "Machete" which is probably a more elegant solution. Cutting edge?...I had some errors with Machete, but found this
.obj to .json Python script. This could go on a server that stores .objs but there's no reason not to batch process the lot off-line.
tl;dl: I have to write a programme to convert .obj meshes into .json files..
I got a mesh loading from a JSON file:
It wasn't difficult to get that working, but there isn't a strict format for a JSON mesh to be in. The exporters and converters were a bit of a let-down, but I already have a C parser of .obj files, so perhaps I can turn this into a little JSON creater in my own layout. Should be the quickest option.
