What do you need to consider when developing for the Apple Vision Pro with the Unity Engine? In this presentation, the findings from different areas of the entire development process will be presented. From 3D rendering to deployment, new requirements and challenges arise that need to be discovered and solved. The optimisation of graphics and performance for the specific display of the Vision Pro, the integration of ARKit for precise motion tracking and the adaptation of the user interface for an immersive user experience are particularly important.
