Please add me to the list of customers who would love to see this function implemented.
We have a Map control that allows our users to switch between 2D and 3D maps, and as it stands when they switch to 3D they lose their current location display. As such I have been tasked with writing a solution to replace the LocationDisplay so that we get a consistent visualisation on both 2D and 3D maps.
The LocationDisplay on 2D maps works really well, and ideally a 3D solution that simply displayed exactly the same symbol with the same animations and draped on the 3D scene would be ideal.
