World Anchors. Why is Vuforia needed?

July 18, 2018 - 6:52am #1

Hello,

I'm in the process of trying to place holograms relative to real world objects, and while reading this forum:

https://developer.vuforia.com/forum/hololens/using-world-anchors-vuforia-extended-tracking?sort=2

listening to all these people talk about how after the first scan they can just position a World Anchor and then they don't need to scan again.

 

Why can't you just position a World Anchor without Vuforia and get this functionality? If the HoloLens is remembering what room it's in, shouldn't that work?

I originally thought you would need to do a Vuforia scan before every run of the app.

Any info is much appreciated. I'm pretty new to all of this and I don't know how to use World Anchors

Hello,

Vuforia brings an important capability to HoloLens – the power to connect AR experiences to specific images and objects in the environment. You can use this capability to overlay guided step by step instructions on top of machinery, or to add digital features to a physical product.

Thanks,

Vuforia Engine Support

Stumbled across this:

https://docs.microsoft.com/en-gb/windows/mixed-reality/persistence-in-unity#getting_the_worldanchorstore

 

"The WorldAnchorStore is the key to creating holographic experiences where holograms stay in specific real world positions across instances of the application."

 

This seems to be exactly what everybody is trying to do!

I'm going to test this tomorrow...
