Most spatial apps load their sky. StratoSync computes it. Metal compute kernels rebuild the Aurora and Star Nest domes on the GPU every display refresh, and Dusty Nebula ray-marches a live field over an 8K procedural star sky — no authored image or video assets. Sunlight is aimed from the real subsolar point, so Earth's day/night terminator matches this moment; the live ISS moves through it on its ~51.6° orbit. Grab Earth, inspect the station, draw around it, or watch together over SharePlay.

Could you build this?
No Writing custom low-level Apple Metal compute kernels for real-time procedural ray-marching at high refresh rates on visionOS demands deep graphics and shader programming expertise.
What it would actually take: The architecture requires visionOS native development in Swift and C++ alongside custom Metal Shading Language (MSL) compute kernels. The hard part is authoring real-time volumetric ray-marching algorithms (e.g., procedural nebulae and star nests) that run within visionOS's strict thermal and render budget (90fps per eye at high resolutions) while integrating real-time orbital ephemeris calculations for astronomical tracking.
