We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.
On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.
So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.
Annotate to HoloLens HUD via UWP Desktop Application?
I am trying to find a solution for the project I am building in Unity. I have a particular task that is giving me some trouble that requires sharing HoloLens data with a PC.
In a two-user scenario, I would like to have my Surface Pro 4 user be able to draw on my HoloLens user's HUD. This would be similar to what is demonstrated in Skype, but I want to make sure the annotations are projected directly on their colliding surface. Generating a gameObject on a particular surface is no big issue, but knowing where the surface is requires HoloLens to send the spatial mapping data out to the tablet user.
My question is this:
How do I send a combined live camera feed and live spatial map from my HoloLens to my Surface Pro 4 from within the multi-user Unity application?
Note: I will not be using the Surface as an AR device. Only for placing objects in the HoloLens user's view.
Note: It is not necessary that I be able to draw, just able to place icons. (I will likely have a library of icons that the Surface user can place, but the icons need to attach themselves to a colliding spatial mapped surface in order to be useful. I can't have them floating in space.)
