Hello!
What is VR?
VR means Virtual Reality

VR is a world that looks real...

but it's generated by a computer

and you can create it!

so, how do we create ours?

Let's start from the basics...

do you know these shapes?

These are all "2D" shapes

Hold on, what does 2D mean?

two-dimensional: width and height

they are "flat" shapes

What happens when we add 1 dimension?

Enter the magic world of

3D

3D means: three-dimensional

width, height AND depth

Let's see if you recognise some 3D shapes

now the fun bit...

With all these 3D shapes we can create

Our own VIRTUAL WORLD!

Enter WebVR

WebVR is a technology that makes it possible to experience VR on your computers and phones

well actually, your mums' and dads' phones :)

let's see how it looks

we can do something more complex

we can use tools to create our worlds (a bit like minecraft)

and we can add interactions (a lot like minecraft!)

how do we enter these virtual worlds?

we can trick our mind that depth is real by using...

Stereoscopy!

Stereoscopy is a technique for creating or enhancing the illusion of depth in an image - wikipedia

Most stereoscopic methods present two offset images separately to the left and right eye of the viewer.

These two-dimensional images are then combined in the brain to give the perception of 3D depth.

to make stereoscopy

on our phones

we can use

a piece of carboard

and 2 lenses

you can make your own

or buy them already made

Demo time!
