Hey thanks for pointing this out since I admittedly hadn't even really considered using anything other than JSON here.

It turns out that the files are roughly the same size since the parser just shuffles the data around to make it easier to pass to your uniforms later.

`f16-model.obj` -> 396.9 kB (396947 bytes)

`f16-model.json` -> 397.5 kB (397534 bytes)

Using pre-parsed `JSON` here helps you avoid needing to parse your `.obj` file during runtime. Plus, since JS runtimes are heavily optomized for JSON, this seemed like a good starting place.

Super open to better alternatives of course!
