I hear a lot about Vuforia, but is that the only option? Can anyone share their preferred approach to creating augmented reality applications?
Hi, ARToolkit http://artoolkit.org/ is open source and royalty free and can target markers and images only. Vuforia is a commercial product, is free but costs $500 per app after 1000 units, has more targeting options (objects, text, world location), is announced to be native supported in a future version of unity, and is a more polished (easy to use) sdk. But there are others too https://www.linkedin.com/pulse/dozens-more-augmented-reality-sdks-than-you-think-here-offermann
Thanks for the info!
