Winter Augmented Reality Meeting 2014

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. Thank you for joining! You can head over to the WARM 2014 website to read more and see the pictures from the event.

Augmented Reality and WebGL

For a project I was reviewing a number of WebGL engines with focus on Augmented Reality. As WebGL is rather similar to OpenGL ES 2.0 there are numerous reasons to use an engine rather than rolling your own code - dealing with matrix transformations and uniform just to name a few things. And there are a number of WebGL engines already out there. Even reviews of WebGL engines can be found aplenty on the web, with varying depth and also scope here and here. Here you find a quick overview of WebGL engines that focuses on Augmented Reality in conjunction with WebGL.

Video Capture Across Devices and Platforms

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.
