Well I going to continue and put objects with images imposed on them into this AR system - which could be quite a quick way to get an organisations logo into AR. Summary In the first post  WebVR playtime 1: Basics of setting up, images and rotating blocks ,  I looked at setting up a scene, rotating an object.   S econd pos t, recapped the basics, then look at adding video, 360 degree video, and models developed elsewhere.  The third post  started looking at using WebVR as part of an augmented reality solution building on the great resource  Creating Augmented Reality with AR.js and A-Frame  by Jerome Etienne, creator of AR.js. This gave us the starting code.  In this post, the ideas are extended further to adding or ...

I am going to try to persuade you that using A-Frame it is not hard to do some simple Augmented Reality (AR) for free, via a browser, but that also can run on a mobile device. Introduction This is part of 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 blocks ,  I looked at setting up a scene and then rotating an object.  In the second pos t, recapped the basics, then look at adding video, 360 degree video, and models developed elsewhere. In this post we are going to start looking at using WebVR as part of an augmented reality solution.
