I have a mountain range scene very similar to this:

displacement anim

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?

  • $\begingroup$ I can export straight to three.js. I've also tried uploading my .blend file straight onto clara.io but the materials and animations don't seem to load with it and there is no animation. I have also noticed once loaded into webGL the model is smoothed and shiny when its supposed to look more like an origami mountain range $\endgroup$

  • $\begingroup$ But can three.js read an mdd file - it is designed for animated mesh data. $\endgroup$

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. Try this tutorial :

Hope that was helpful

  • $\begingroup$ I have already tried this, unfortunately the moment i add a bone and parent it to the mesh three.js refuses to export saying that the bones arent valid $\endgroup$

    $\begingroup$ Recently the threejs Blender JSON exporter has been removed. I would suggest using the glTF Blender exporter (github.com/KhronosGroup/glTF-Blender-IO) instead, which supports shape keys and can be imported to three.js as well. $\endgroup$
