SoftwareRenderer is a drop-in renderer for Three.js that can be used on the server and the client,
if you need to be GPU independent.
Primarily performance. As this renderer does not have access to GPU acceleration and GPU shader units, it's much much slower than the CanvasRenderer or WebGLRenderer.
In addition, you'll have to use
THREE.DataTexture instead of a normal
THREE.Texture for textures when you're in a headless environment (i.e. node.js).
So far I have tested 0.69 and 0.71. Please tell me if you tried it with other versions as well :-)
