WebGL/3D works fine, just with some additional dependencies (e.g. mesa drivers) and a little more setup in Nodejs to create the context and copy the framebuffer to node-canvas to do the image encoding.
Here's a little 3D animation I've rendered using a similar technique (plus WebGL) in a docker container:
The main thing to watch out for is whether you need specific WebGL extensions that might not be supported. Array instancing is the main one I use, which is supported.
