I have been looking at creating an augmented reality application. Can anyone suggest a preferred technology platform to start writing an application of this kind.
You can use Nyartoolkit for java on Windows and Linux platforms
You can install using http://sixwish.jp/Nyartoolkit/Java/section01.en/
Also you can check http://fivedots.coe.psu.ac.th/~ad/jg/ch165/index.html for Augmented Reality with NyARToolkit e-book and samples.
