WebVR playtime 2: video, 360 video and objects

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) . In the first post WebVR playtime 1: Basics of setting up, images and rotating blocksI looked at setting up a scene and then rotating an object.

In this post, I going to recap the basics, then look at adding video, 360 degree video, and models developed elsewhere.

1. The approach and setting up

I chose 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. In Thimble though try to keep the image or video file sizes small.

You can pretty much treat it as HTML, after you have added the script file shown in bold.
<!DOCTYPE html>
    <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>


The items to be add all go between <a-scene> and </a-scene>:
      <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-text value="Hello" color="black" position="0 1.8 0.5" width="10"></a-text>
      <a-sky color="orange" ></a-sky>

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

2. Adding video
Actual in some ways it as easy to add video as adding an image, at it's simplest adding src="" with either the URL or relative filename in the speech marks can be used for both images and video. Alternatively using <a-video src=""></a-video> combination with again the filename or URL between speech marks adds a block and pastes the video on top. The video below shows a worked example of these two approaches

3. 360 degree video.
A-Frame allows 360 degree to be incorporated into the scene using the <a-videosphere> tag. The video below shows a worked example of this. The video below shows another worked example.

4. 3D objects and Assets
We can also add 3D models that others have developed into our scene. In the video below a Penguin, defined externally using .obj for the model and .mtl for the material, is loaded into the scene.
