we would like to invite you to the 9th Winter Augmented Reality Meeting (WARM2014) to be held on February 26-27, 2014 in Graz, Austria. WARM is a workshop plus optional skiing event (February 28-March 2, 2014). It was founded in 2005 and has since grown in numbers of attendees each year. Head over to the WARM 2014 website to read more, submit a presentation proposal or register yourself as an attendee.
For a project I was reviewing a number of WebGL engines. As WebGL is rather similar to OpenGL ES 2.0 there are numerous reasons to use an engine rather than rolling your own code. And there is plenty of choice of WebGL engines. Also reviews of WebGL engines can be found aplenty on the web, with varying depth and also scope here and here. Now, I would like to throw one in the mix that focuses on AR in conjunction with WebGL.
Working with AR technology starts rather mundane with getting some sort of video from a video source, usually an USB webcam or built in camera in a phone. One would believe that is the easiest part. But trust me it is not. There are more APIs and approaches out there then you care to learn about. Everybody trying to do things different or easier. And for what is worth it, the underlying device drivers are doing the "right thing" sometimes, but not always. One has to deal with threads that are spawned by the underlying APIs and whatever format the frames come up.
