SplatStage
4Walk inside photoreal Gaussian-splat scenes on Vision Pro via visionOS 27's native splat API.
The story
Stand inside a photoreal Gaussian-splat environment on Apple Vision Pro, rendered by visionOS 27's native RealityKit GaussianSplatComponent — then light it like a film set with the new cinematic RealityKit stack: projective-texture spotlights, soft shadows, ray-traced reverb meshes. Built the day after WWDC 2026 against Xcode 27 beta 1, with the device-proven beta-1 recipe (chunking, buffer alignment, colorSpace) documented for everyone who hits the same walls.
Highlights
- ✦visionOS 27 native GaussianSplatComponent — among the first public recipes
- ✦Cinematic RealityKit lighting: projective spotlights, soft shadows, RT reverb
- ✦The beta-1 gotcha list: chunking, buffer alignment, colorSpace
- ✦A/B benchmark vehicle vs. custom MetalSplatter rendering
