How is Virtual Reality Created?

 



There are two important parts to creating virtual reality.

All images must be wholly three-dimensional, and proportionately sized. This makes for a completely absorbing experience that is theoretically indistinguishable from the world around us.

All motions made by the user must be captured, and replicated in the virtual reality environment. This doesn’t just mean physical movement of limbs – Virtual reality should also acknowledge movements of the eyes, and amend the visual experience of the environment accordingly.

This requires a very particular skillset. Creating virtual reality is very different to basic computer coding, or the creation of a two-dimensional video game environment.

How to Make a Virtual Reality Video



Let’s take a look at the creation of a virtual reality video of your very own. If you’re going to tackle this, you’ll need certain hardware and software. This includes:

  • An Android smartphone or tablet (genuine Virtual reality is not available on iOS.)
  • A headset (you won’t need bells and whistles – making your own from cardboard will be fine.)
  • Unity3D and Google Virtual Reality SDK installed on your computer (again, this will need to be Windows-based, not Apple.)
  • 360 degree video footage (shoot your own if you have an appropriate camera or source stock footage from elsewhere)

Once you’re ready, sample instructions for creating a video in virtual reality would be:

  • Build a shape (the guide we’re using recommends a sphere) into your Unity scene.
  • Reverse the settings of this shape (also known as “flipping the normals.”)
  • Project your 360 footage inside the shape that you created.
  • Set up your headset.
  • View the video through your phone, and have your mind blown!
