Hologram to face the user
I am trying to implement a holographic screen, which should face the user as soon as the user is stationary at a position.
In the implementation, when the user is moving, the hologram should NOT continuously change orientation to face the user. However, as soon at the user stops moving, and fixes position, the hologram should now orient to user's direction, facing the user. I went through bill boarding to implement this. I would like to know if bill boarding continuously reorients holograms to face the user; or does so only when user becomes stationary at a position?
Thanks in advance!

Hey, @John_Smith1

Hi Stepan_Stulov,
Thank you for your detailed response.
I understand from your points above that it is possible to produce rotation to cause hologram face the user, at a trigger, and the trigger can be when the user stops moving. In this manner, the holograms will face the user when he/ she stops.
Please confirm if it is appropriate to implement the OnTriggerEnter() in place of Update in the script at source: https://github.com/Microsoft/HoloToolkit-Unity/blob/master/Assets/HoloToolkit/Utilities/Scripts/Billboard.cs ?
Also, any source link which explains such an implementation or use of trigger for billboard would be highly appreciated!
Thanks again,
Regards,
John

No, you'd rather adjust the Billboard script so that it doesn't
continuously look at the camera but only when some kinda of isLooking flag is set to true so you can choose when to billboard.
And then you will implement your stationarity detection system which will either be a stopping self detection camera or camera with landmarks, depending on which you want.
Finally you will wire the events of the camera starting and stopping stationarity with enabling and disabling your billboards' isLooking flag.
This is all just a suggested architecture, it's up to you at the end of the day.
PS: Things to keep in mind if you go the landmarks path:
