Processing and Virtual Reality Headset

edited June 2017 in Android Mode

Hi everybody,

I'm currently working on a design project which represent a virtual world. My processing is a land with a camera in movement, giving the impression of surfing. I would like to make it in virtual reality, how I can do virtual reality with a processing ? Is it easy ? How it works ?

Many thanks !!
