Everything we have in our app can be shared. Data, holograms, coordinate systems, you name it. But there are different ways we can set this up. Of course, it all depends on the scenario and what it is you want to achieve. Let us have a look at some of these along with the way to set up networking.
First, we can load data from an external server. This is something we have been doing for ages, but it is a good starting point. A lot of data resides in a cloud solution somewhere and it would be nice to have access to that.
Things get a bit more interesting if we want to talk to another HoloLens. We have two choices here:
- Use a hub or centralized server
- Connect directly to the device
Again, what you choose depends on your needs.
If you need to have multiple devices sharing data, I suggest you go the hub route. This scales much better and you have much better control over the life cycle of the data flow. Remember, Holographic apps are UWP apps and therefore they may suspend and resume...
