Virtual Reality (Fully Immersive) Apps Port an existing virtual reality game or create a new fully immersive experience, replacing the player’s surroundings with your own environments. Mixed Reality (Immersive) Apps Mix content with passthrough to create immersive experiences that blend digital content with the real world. Use Unity’s PolySpatial technology to run your content alongside multiple applications while in the Shared Space. Windowed Apps Run content in a window that a user can resize and reposition in their space. This is the easiest way to bring existing mobile and desktop applications to visionOS, and is the default mode that content will run on when targeting the visionOS platform.
