#VR
**Virtual Reality (VR)** is a computer-generated 3D environment that simulates a real experience. The level of interactivity can vary from passively observing to device-assisted interactions.
Examples:
* <a href="https://www.youtube.com/watch?v=hEK-J3ZgCZA">Tilt Brush</a>
* <a href="https://experiments.withgoogle.com/webvr/konterball">Konterball (ping pong in VR)</a>

# Intro to A-Frame
**A-Frame** is an open source framework for developing WebVR, based in HTML. Because it is cross-platform, we can experience A-Frame projects using anything from an Oculus Rift, to the browser on our desktop computer.
*Navigate within a scene by using WASD or arrow keys. Click and drag to turn.*

#CODE! (Specifically HTML)
* We use browsers to see websites
* Browsers don’t understand English - but they do understand HTML!
**HTML is written with tags.**
Tags usually come in pairs — an opening tag and a closing tag — to wrap the content. Note the closing tag has a forward slash (`/`).
```html
<tag> opening tag --- closing tag </tag>
```
HTML tags describe the content inside of them to the web browser.
```html
<h1>This tag describes a heading</h1>
<p>This tag is for paragraphs.</p>
```

# Primitives
A-Frame uses HTML elements called **primitives**. These can be customized using HTML attributes (e.g. `color="red"`).
* **Position** defines the position in 3D space (X,Y,Z) - measured in meters
* X = left-right
* Y = up-down
* Z = forward-back
* **Rotation** defines the orientation in 3D space (X,Y,Z) - measured in degrees
* X = pitch
* Y = yaw
* Z = roll
</script>
</section>
<section class="slide" data-markdown>
<script type="text/template">
#Challenge
We can customize elements by adding or changing their attributes.
An attribute looks like: `color="blue"`
**Try out a few of the following:**
* Change the colour
* Change the rotation
* Change the position

# Building our virtual world
<strong>We'll go through the following steps together:</strong>
1. Changing the background image
1. Adding textures
1. Adding more 3D shapes
1. If time: Adding animation
1. Saving and sharing projects
</script>
</section>
<section class="slide" data-markdown>
<script type="text/template">
# Asset Management System
This system helps your browser cache images, in order for the scene to load more quickly. We can use the asset management system by adding a new primitive called `<a-assets>`.
1. Add an `<a-assets>` opening and closing tag just inside of your `<a-scene>`
```html
<a-scene>
<a-assets>
</a-assets>
<!-- ... -->
</a-scene>
```
</script>
</section>
<section class="slide" data-markdown>
<script type="text/template">
# Step 1: Change the Background Image
1. Locate your image in the assets folder and copy the image URL <br> 
1. In the index, replace the background URL with your new image URL
1. Update the `<!--comment-->` above the `<img>` with information on where your image was taken from
1. This should update the image used in the `<a-sky>` entity
<em>Any new images will need to be added in between the `<a-assets>` tags. They will also need a new `<img>` element with an id (name) and src (url).</em>
```html
<a-scene>
<a-assets>
<img id="background" src="https://cdn.glitch.com/linktoimage1"/>
</a-assets>
<a-sky src="#background"></a-sky>
<!-- ... -->
</a-scene>
```
</script>
</section>
<section class="slide" data-markdown>
<script type="text/template">
# Step 2: Add Textures
1. Copy the image URL (click on image > “Copy Url”) (same as “Step 2”)
1. In the index, replace the ‘concrete’ URL with your new image URL
1. Update the `<!--comment-->` above the `<img>` with information on where your image was taken from.
1. You may want to update the name, as well - from ‘concrete’ to whichever word describes your new texture. <strong>Be sure to update the name in both places</strong>: in the `<img>` element and the 3D shape you are applying the texture to.
1. If adding textures to new shapes, you will need to add a src to that shape (see example below)
```html
<a-scene>
<a-assets>
<img id="concrete" src="https://cdn.glitch.com/link-to-new-image"/>
</a-assets>
<a-sphere src="#concrete" position="0 2 -3" radius="0.5" shadow></a-sphere>
<!-- ... -->
</a-scene>
```
</script>
</section>
<section class="slide" data-markdown>
<script type="text/template">
# Step 3: Add More 3D Shapes
1. Find more 3D shapes in the A-Frame reference: [aframe.io/docs](https://aframe.io/docs) → look under the “Primitives” section <br> 
1. Add new primitives in between the `<a-scene>` tags, underneath `</a-assets>`
```html
<a-scene>
<a-assets>
<!-- ...-->
</a-assets>
<!-- put new primitives here-->
<a-sphere src="#concrete" position="0 2 -3" radius="0.5" shadow></a-sphere>
<a-plane position="0 0 -4" rotation="-90 0 0" width="4" height="4" color="pink" shadow></a-plane>
<a-sky src="#background"></a-sky>
</a-scene>
```
</script>
</section>
<section class="slide" data-markdown>
<script type="text/template">
# STRETCH GOAL: Adding Animation
We can use the `animation` attribute to animate entities within our scene. Add it inside of the object you would like to animate.
```html
<a-box position="-1 0.5 -3" rotation="0 45 0" color="#4CC3D9" shadow animation="property: position; to: -1 1.5 -3; dir: alternate; dur: 2000; easing: linear; loop: true;"></a-box>
```
* **Property** specifies which part we are animating (e.g. position, rotation, scale.. even material.color!)
* **To** is the value we are animating it to (e.g. 1 meter higher than the original position)
* **Dir** is the direction of the animation (between `from` and `to`)
* **Dur** is how long it takes (in milliseconds)
* **Easing** indicates whether or not it speeds up/down
* **Loop** is the amount of times this happens (put a number here, or `true` to loop forever)
See the <a href="https://aframe.io/docs/0.9.0/components/animation.html">Animations documentation</a> for more options!

# Instructions
Follow these steps to view your A-Frame scene using VR Viewers:
1. Rename your project (if you haven't already done so) <br> 
1. Open up a browser and go to your project's URL (same as 'Show Live') <br> 
1. Click on the Google Cardboard icon <br> 
1. Place your mobile device in the viewer and enjoy!
*Audio will not play on mobile phones running iOS. Use Androids with Google Cardboard if you'd like to experience sound.*
