This is a rough roadmap for porting the plugin from 3.x to an extension for 4.0. Will probably change a lot and input is appreciated!

• Implement HoloPlayManager singleton class
  • This class should manage all connected HoloPlay devices, e.g. keep a list of connected devices so we can supply all HoloPlayVolumes with a dropdown list. Since it's a singleton it can also manage static content like the compiled lightfield shader. We could also give the user access to state functions such as hpc_InitializeApp but this might be more inconvenient than useful.
  • Poll for devices using hpc_RefreshState and hpc_GetNumDevices etc. at sensible intervals/times.
    • Maybe when a HoloPlayVolume node is instantiated/selected in the editor or when the device list dropdown is accessed in the editor? Any ideas?
  • Use RenderingDevice to compile the lightfield shader (shaders require some run-time tweaking to make them compile in Vulkan)
  • Retrieve a list of all connected devices (might work with hpc_GetNumDevices and iteration using hpc_GetDevice*
    • Dictionary support is not complete in the current C++ bindings so this could still be improved to contain more info.
  • Initialise and close the app on the HoloPlay service
    • initialize_app compiles the shaders and initialises the app with the HoloPlay Service. hpc_close is called automatically.
  • Implement state functions
    • get_holoplay_core_version
    • ...
  • ...
• Implement HoloPlayVolume class
  • Basically the same as the HoloPlayVolume class from the 3.x plugin but does not store static data such as the compiled shader.
  • Inherits Node3D
  • Retrieve a list of available devices from HoloPlayManager
  • Use DisplayServer for windowing logic (no platform-specific code for context sharing and GLFW needed anymore.)
  • Use RenderingDevice or whichever class is used for this in Godot 4.0 to render the quilt using the compiled shader from HoloPlayManager
  • ...
• Reimplement editor gizmo.
  • Should be a relatively straight port from the 3.x version.
• Reimplement HoloPlayRecorder node
  • Can also be ported from 3.x althought this could probably use some improvements as well.

What is missing?
