I recently utilised Vuforia for an AR demo for iOS devices (via Unity 3D) and was pleasently surprised with its ease of use, realiabilty and robustness.
However its a real shame that currently it does not support publishing to standalone/desktop applications. This is really limiting as i've worked on a number of AR projects in the past, with competitor SDK's that I'd much rather switch over to using Vuforia for. It would also make a great deal of sense in terms of being able to develop once but publish to Android, iOS and Mac/PC desktop, thus unifying all our AR development.
Is there any reason why you are not currently supporting desktop/standalone?
Using the Unity package its clear that the SDK itself works in a desktop environment, even if it is just the Unity editor, so it would seem like most of the work needed for desktop is already done?
Enabling publishing of standalone/desktop apps would pretty much make Vuforia a one stop shop and our prefered AR SDK.
So whats preventing this from happening?
