Apple recently unveiled the Vision Pro. This type of device is mostly designed for augmented reality (AR), in the sense that it should be able to throw 3D models and rendering combined into a camera.
Normally with pass-through AR, one would expect to get the camera feed as an image and maybe some environment cubemap generated from the camera to apply proper lighting into the objects.
This is a walkthrough to the Godot codebase over time. I can't publish full repositories, but I will put here the interfaces of some APIs including the year they were created and how they looked like at the time.
This was the first version of the engine as such. It was later on used to create Regnum Oline. This is source code where I am sure I can still put legally here. Here are some class interfaces.
Mesh class:
The main goal is to implement a GPU driven renderer for Godot 4.x. This is a renderer that happens entirely on GPU (no CPU Dispatches during opaque pass).
Additionally, this is a renderer that relies exclusively on raytracing (and a base raster pass aided by raytracing).
It is important to make a note that we dont want to implement a GPU driven renderer similar to that of AAA/Unreal, as example.
