With the model derivative API peeling itself away from the View and Data API, you can now translate stuff into OBJ at API level. Before you had to load up a viewer instance, which only takes in svf translated with this API. Now you can just load the OBJs that you've translated into your three.js scene!
I translated a f3d model that I have on hand into an obj, and loaded it into a scene. It's this car:
The API lets you translate parts of the model by specifying the part of the hierarchy you want to translate. So I translated just the suspension.
I just modified the three.js example code that lets you load your obj. Just replace the url of where the obj is.
THREE.MeshPhongMaterial instead of mapping a texture myself.
Here's the relevant part of the code:
Now you have a weird-ish looking blue suspension in your three.js scene!
