SplatWorld, a new app from developer xChester, is live on Vision Pro. The app opens any Gaussian Splat capture and applies real-time visual effects that users can tune on the fly.
Key details:
Effect set: crystal reveals, aurora loops, studio relighting, painterly palettes
Workflow: works with existing Gaussian Splat captures rather than producing new ones
Tunability: all effects render in real time with parameters exposed to the user
The Performance Layer: SplatWorld sits in a different part of the splat pipeline than most Vision Pro tools released so far.
Most existing apps focus on either capturing splats or viewing them. xChester's pitch in the launch post is that users "open any Gaussian Splat capture, then make it perform." The build took "months of 'just one more effect,'" according to the developer.
The four effect categories suggest a presentation-focused tool:
Crystal reveals restyle captured surfaces with translucent and refractive treatments
Aurora loops layer animated atmospheric elements over the scene
Studio relighting changes the lighting of the captured environment after the fact
Painterly palettes apply non-photorealistic color treatments
Pricing, supported file formats, and detailed compatibility notes have not been published in the launch announcement.
A Growing Vision Pro Splat Stack: SplatWorld lands in an ecosystem that has filled out in stages.
Three other apps cover adjacent parts of the pipeline:
Spatial Fields is a full-fidelity viewer across iOS, visionOS, macOS, and tvOS, with spherical harmonics support and Apple TV streaming for group viewing
Splat Studio handles on-device creation, converting Photos library images into 3D scenes through Apple's SHARP model in roughly 20 seconds per image
MetalSplatter is an open-source Swift and Metal viewer that doubles as a developer library for building custom splat tooling
SplatWorld occupies a spot none of those cover: applying effects to splats as a creative layer, rather than treating the capture as a fixed asset.
Capture, View, Perform: For XR production teams working on Vision Pro, the Gaussian splatting pipeline has matured into discrete stages.
SplatWorld's real-time tunability is the part that matters for production use. A scanned location set can be restyled into a stylized environment with parameter tweaks, without re-capturing or re-rendering. That moves splats closer to a working creative format rather than a one-shot photogrammetric output. How the effects hold up under closer scrutiny will depend on hands-on testing as more material surfaces from the developer.
