The document provides an overview of WebVR and WebXR, highlighting their APIs for immersive web experiences, compatibility with various devices, and use cases such as 360 tours and gaming. It discusses the A-Frame framework for building virtual reality experiences with simple HTML and the inclusion of 3D objects using components. Additionally, it includes coding examples and resources for creating VR environments and components.

16. A-Frame
web framework for building
virtual reality experiences

17. • VR Made Simple
• Declarative HTML
• Cross platform
• Component based
• Tool agnostic
• Inspector
• Community + Slack
A-Frame

18. A-Frame Components
<a-scene>
<a-box position="-1 0.5 -3" rotation="0 45 0" ></a-box>
<a-sphere position="0 1.25 -5" radius="1.25" ></a-sphere>
<a-cylinder position="1 0.75 -3" radius="0.5" height="1.5" ></a-
cylinder>
<a-plane position="0 0 -4" width="4" height="4" ></a-plane>
<a-sky color="#ECECEC"></a-sky>
</a-scene>

19. A-Frame

20. Glitch
• https://glitch.com
• Code in the browser
• Custom url for testing
• Remix other projects

21. WebVR - Primitives
• https://aframe-start.glitch.me
<a-scene>
<a-box position="-1 0.5 -3"></a-box>
</a-scene>
Other Primitives:
• a-entity
• a-sphere
• a-cylinder
• a-plane
• a-sky
Other Attributes:
• rotation=“X Y Z”
• color = “red”
• scale=“X Y Z”
Other:
• Nesting elements
• Inspector

22. WebVR - Textures
• https://timmykokke.com/360.jpg (equirectangular)
• http://texturelib.com/
• “src” attribute with URL or ID
src="https://url.com/image.jpg"
<a-assets>
<img id="boxTexture" src="https://url.com/image.jpg">
</a-assets>
…
<a-box src=“#boxTexture”></a-box>

23. WebVR - Cursor
<a-camera position=“0 1.6 0”
<a-entity cursor="fuse: true; fuseTimeout: 500“
position="0 0 -1"
geometry="primitive: ring; radiusInner: 0.02; radiusOuter: 0.03"
material="color: purple; shader: flat">
</a-entity>
</a-camera>

24. Webvr – Custom Component
AFRAME.registerComponent('change-color', {
schema: {
color: {default: 'green'}
},
init: function () {
this.el.addEventListener('click’,() => {
this.el.setAttribute('material', 'color', this.data.color);
})
}
});
<a-sphere color="blue" change-color="color:pink"...

25. A-frame – what else?
• Systems
• Animations
• Shaders
• Three.js
