One, Two, Three and to the FLAR
Augmented reality has been a recent darling of the tech and advertising communities, and has been used recently in games, for products like Topps baseball cards and the USPS priority mail box and by brands like Doritos and BMW to supplement campaigns.
It’s not hard to find demos of AR in action online, but very few of them tell you about the technology behind making AR happen. Our interactive developer Jason Bejot looked into a Flash-based AR method, the FLAR toolkit. This brings AR to anyone with Flash, rather than limiting it to people who have purchased specific software. To implement the FLAR toolkit, you need Flash/Flex, Papervision 3D/Away 3D, a printer and a webcam.
Jason created a demo starring galactic bounty hunter Boba Fett to try out the FLAR toolkit and show the rest of us what it could do. Boba Fett is an unaltered Quake II model from a model pack. Since Papervision handles those files natively, it was ultra easy to throw everything (FLARToolkit, Papervision and Boba Fett) together and have it work. In fact, it took Jason no more than two hours, including producing the code to make Boba Fett walk.
FLAR toolkit is a cool step in AR, but the toolkit has limitations. It’s processor intensive; the Boba Fett demo used 40-60 percent CPU. There’s limited marker tracking, recognizing a low number of markers, no color, and low resolution. The toolkit library is based on an old version, so it has limited features and isn’t actively developed. But even with limitations in mind, we still think any development that opens AR and other emerging technologies up to more people is definitely a step in the right direction.
