The ARVR interface is a template class ontop of which we build interface to differt AR, VR and tracking SDKs.
|
||
|
|
The idea is that we subclass this class, implement the logic, and then instantiate a singleton of each interface
|
||
|
|
when Godot starts. These instances do not initialize themselves but register themselves with the AR/VR server.
|
||
|
|
|
||
|
|
If the user wants to enable AR/VR the choose the interface they want to use and initialize it.
|
||
|
|
|
||
|
|
Note that we may make this into a fully instantiable class for GDNative support.
