WebVR playtime 1: Basics of setting up, images and rotating blocks.

This is going to be a short series of articles about some experiments with WebVR Web based Virtual Reality - in this case based on the wonderful A-Frame (https://aframe.io) . Ok, a bit of context, I have been working with some MSc students on this area and we have been exploring this area together - I love learning from and with my students.

Firstly, it is great fun and nowhere near as hard as I thought it was going to be when I first started. 

1. The approach
My approach is to use A-Frame (https://aframe.io) inside Thimble (https://thimble.mozilla.org ). Thimble was selected for four reasons it is an online editor,  simple to use, it is free and you see the preview immediately. Its main downside is the size of images and videos has to be relatively small and not too many of them.

2. How easy is it?
You can pretty much treat it as HTML, after you have added the script file shown in bold.
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <script src="https://aframe.io/releases/0.7.0/aframe.min.js"></script>
  </head>
  <body>
    <a-scene>

    </a-scene>
  </body>

</html>
The items to be add all go between <a-scene> and </a-scene> with a parent-child relationship; for example A block of text saying Hello in black and making the sky orange are all 'children' of <a-sceme>:
      <a-text value="Hello" color="black" position="0 1.8 0.5" width="10"></a-text>
      <a-sky color="orange" ></a-sky>
For example
    <a-scene>
      <a-text value="Hello" color="black" position="0 1.8 0.5" width="10"></a-text>
      <a-sky color="orange" ></a-sky>
    </a-scene>

The video below shows setting up and adding a box to the scene.



This next video takes this a little further by adding rotation to an object.



In this video mapping an image to an object and changing camera position is looked at.




In later posts some further ideas will be explored.
