Please support for .obj .dae models with cannon.js

[anothercoder2]

For developing any serious game with three.js or cannon.js we are going to be required to load models.
From my research so far it seems that with cannon.js we can only use three.js json models.
Converting a simple 1mb .blend file results in a 29mb .json model.
This file size is impractical for any online game.
I have opened a issue for three.js
Blender to json export file size #6455
mrdoob/three.js#6455
Not sure what the response will be but if the cannon folks can support the .obj or .dae that would help taking three.js and cannon.js forward.

SceneVR uses .obj models with cannon.js. You can convert the mesh data (that is loaded using any loader) into a cannon.js 3d model.

Based on my experience, I don't think either format is worth the effort.

@anothercoder2 @bnolan @ioquatix How do you convert the mesh data to a cannon js model. There is nothing in there docs that have a custom type http://schteppe.github.io/cannon.js/docs/ What custom types or classes are needed to make this happen? Thanks

I've written some utilities for converting THREE.Mesh objects (loaded from any format) to CANNON.Shape objects: https://github.com/donmccurdy/three-to-cannon

It's not perfect (handling nested meshes is a bit tricky), but works well enough especially with the bounding box or convex hull options.
