Native GPU training
Train 3D Gaussian Splatting scenes directly on the Apple Silicon GPU using Metal, with no cloud upload required.
RadianceKit
RadianceKit is a native Mac app for 3D Gaussian Splatting that imports photos or video, trains locally on Apple Silicon, and lets you edit and export scenes in one workflow.
3D Gaussian Splatting app for Mac
RadianceKit is a native Mac application for 3D Gaussian Splatting. It turns photos or video into a photorealistic 3D scene by handling import, camera alignment, training, editing, preview, and export in a single workflow.
The app is designed for Apple Silicon Macs and uses Metal GPU compute for local processing. According to the source, it does not require a cloud service, a command-line workflow, or a Python setup, which makes it a practical option for users who want an all-in-one desktop tool for reconstructing scenes on their Mac.
Features
Simple and expert workflows
Choose a guided Simple Mode or switch to Expert Mode with a three-panel layout, project navigator, 3D viewport, inspector, live loss curves, and export controls.
End-to-end capture pipeline
Import photos or video, let Apple Photogrammetry align the camera positions, then train and preview the scene in the same app.
Interactive Gaussian editor
Clean up reconstructions in the viewport by selecting and deleting stray regions with a brush tool, then undo changes if needed.
Multiple export formats
Export scenes as PLY, Compressed PLY, SPZ, glTF, .splat, or SOG, and create orbit videos or self-contained web viewers.
Mac-focused local app
Run the workflow locally on an Apple Silicon Mac with support for M1, M2, M3, and M4 chips, and macOS 26 Tahoe or later.
Use cases
Single-user Mac workflow
Create photorealistic captures from ordinary photos or a slow video when you want a finished 3D scene without building a command-line pipeline.
Quick guided reconstruction
Work from a guided process when you want the app to handle the main steps for you, from importing media to producing a scene.
Detailed reconstruction control
Use the expert workspace when you need more control over training parameters, live loss curves, and export settings for professional scanning work.
Cleanup and refinement
Remove floating artifacts or unwanted scene parts after training by brushing them out directly in the 3D viewport.
Sharing and downstream delivery
Export to common 3D formats or share a self-contained viewer when the result needs to be passed along without extra software.
Pros and Cons
Pros
- Keeps the workflow local on the Mac, with no cloud upload required for processing.
- Combines import, alignment, training, editing, preview, and export in one app.
- Offers both a simple guided mode and an expert workspace for more control.
- Supports several export formats and shareable outputs, including orbit videos and web viewers.
- Can open existing splats such as .ply, .spz, and .splat for viewing without retraining.
Cons
- Requires an Apple Silicon Mac running macOS 26 Tahoe or later.
- The source does not provide a Windows, Intel Mac, or web version.
- Native 360 and fisheye ingest are described as roadmap items, not shipped features.
FAQ
What does RadianceKit do?
RadianceKit is a native Mac app that handles the full Gaussian Splatting workflow: import photos or video, align cameras, train, edit, and export in one place.
Do I need Python or other tools to use it?
No. The source says RadianceKit is a complete workflow inside a single app, with no command line, no Python setup, and no external software required.
Does RadianceKit process data in the cloud?
RadianceKit runs locally on an Apple Silicon Mac through Metal. The source states that your photos and scenes stay on your device and no internet connection is required for processing.
What Mac does it require?
RadianceKit requires an Apple Silicon Mac (M1 or later) running macOS 26 Tahoe or later. The source also recommends 16 GB of RAM for larger scenes.
Which file types can it import and export?
RadianceKit imports photos and video for training, and it can open existing splats such as .ply, .spz, and .splat. It exports PLY, Compressed PLY, SPZ, glTF, .splat, and SOG, plus orbit videos and self-contained web viewers.
