Blender scene animation exported to Three.js without bones or skinning? I have a mountain range scene very similar to this: 



The mesh is a simple plane extruded to form a low poly mountain range, the animation uses 3 shape keys, a base and 2 for random vertices displacement. This is then keyframed 7 times over 250 frames to make the surface look like it's continually subtly shifting.

My intent is to use the Three.js output to embed the 3D animation into a web browser. However, it seems the only examples I can find use "skinning" and "bones". 

Is it possible to do without bones or is there an alternative that isn't embedding as a video?
Not sure if this is what you need, but it's a plugin for blender to export json for threejs.

https://github.com/mrdoob/three.js/tree/master/utils/exporters/blender

It has the instructions on how to install it.

To animate my stuff I use shapekeys.
