Apple

Apple added Gaussian splats to RealityKit in visionOS 27, presented in WWDC26 session 279. A splat is represented by GaussianSplatResource, backed by GaussianSplatResource.BufferResource, and placed in a scene through GaussianSplatComponent. The API is format agnostic. An application supplies position, scale, rotation, opacity and spherical harmonic buffers directly, and Apple publishes no splat file format of its own, so parsing PLY, SPZ or SOG remains the application's responsibility. Until this, splat playback on Apple hardware came from third party work including MetalSplatter and Spatial Fields, alongside Apple's own use of the representation in Apple Maps Flyover.
