That's just irritating. I had a post here regarding my first Augmented Reality demo app using the FLARToolkit. Apparently, there is a bug in BlogEngine that when you edit a post, sometimes it will erase your post. Nice.
Ok, So last Thursday, I discovered the FLARToolkit which is an open-source library for creating AR applications in Flash. The project is contained in the Spark Project library. After playing around with the FLARToolkit and the FLARToolkit Start-Up application, I created my first one in Flash using the start-up demo as a base.
My version is located on my demo server at FlexMafia.
