I would highly recommend Cardboard. I haven't used WebVR, and I'm not certain how good its Cardboard support is. I'd suggest just starting with Three.js as it is, and then use StereoEffect to get the pseudo-stereoscopic view for Cardboard. There's sample code here, and it works on Chrome, Safari and even Edge. https://vr.chromeexperiments.com/ https://vr.chromeexperiments.com/ Unity with the Cardboard SDK is very easy to dive into as well.
