Design aiperformancehardware RadianceKit
RadianceKit provides a native macOS app for 3D Gaussian Splatting, enabling local training and editing of photorealistic scenes using Apple Silicon GPUs.
What: The application handles the entire 3D Gaussian Splatting workflow—from importing photos/video to training and exporting—entirely on-device without needing Python, command-line tools, or cloud resources.
Why it matters: Bringing complex research-heavy tasks like Gaussian Splatting to native, consumer-grade apps significantly lowers the barrier to entry for 3D reconstruction outside of academic or cloud-based environments.
Deep dive
  • Supports training 3D Gaussian Splats directly on Apple Silicon chips using Metal.
  • Provides a full workflow including import, alignment, interactive editing, and export.
  • Includes a 'Simple Mode' for automated processing and 'Expert Mode' for granular parameter adjustment.
  • Handles various input types including standard photos, video, and 360-degree footage.
  • Offers six export formats: PLY, Compressed PLY, SPZ, glTF, .splat, and SOG.
  • Requires macOS 26 Tahoe or later and recommends 16GB of RAM.
Decoder
  • 3D Gaussian Splatting: A technique for real-time scene reconstruction that uses millions of tiny 3D ellipsoids (splats) to represent a space, allowing for high-fidelity interactive views of captured scenes.
  • Metal: Apple’s proprietary low-level graphics API that provides direct access to the GPU, used here for hardware-accelerated training of 3D models.
  • NeRF (Neural Radiance Fields): A deep learning method that uses a neural network to represent a 3D scene from 2D images; 3D Gaussian Splatting is often considered a faster, more efficient successor to NeRF.

3D Gaussian Splatting on Your Mac

Create photorealistic 3D scenes from photos and videos — powered entirely by Apple Metal GPU compute on your Mac. A fast, local alternative to cloud-based NeRF and photogrammetry tools.

A complete Gaussian Splatting workflow on Mac — import, train, edit and export in a single app. No separate tools, no Python, no cloud.

Features

Native GPU Training on Apple Silicon

RadianceKit runs 3D Gaussian Splatting training directly on Apple Silicon using Metal. No cloud upload required — your data stays on your machine. Runs on every Apple Silicon Mac, from M1 to M5, for fast 3D reconstruction from photos.

Simple and Expert Mode

Simple Mode guides you step by step: import photos, press Start, and get a 3D scene. Expert Mode gives you a three-panel layout with project navigator, interactive 3D viewport, and a full inspector for training parameters, live loss curves, and export options — ideal for professional 3D scanning workflows.

360° and Panorama Import

Drop 360° footage straight in — equirectangular, stereo 360° (top/bottom and side-by-side), cubemap, equi-angular cubemap (YouTube), fisheye 180/200° and partial panoramas, as photos or as video. The projection is detected from the file's metadata and can be set by hand whenever that metadata was stripped. RadianceKit unwraps every frame into overlapping perspective views that train like any other capture. Shoot from several positions — a single panorama has no parallax — and a 5.7K or 8K camera pays off, because each 90° view uses only a slice of the source resolution.

Six Export Formats

Export your Gaussian Splatting scenes as PLY, Compressed PLY, SPZ, glTF, .splat, or SOG. Create orbit videos or self-contained interactive web viewers — ready to share without any additional software.

Interactive Gaussian Editor

Select and delete regions directly in the 3D viewport. Remove floating artifacts or unwanted parts of the scene with a brush tool, then undo if needed. Fine-tune your 3D reconstructions with precision.

How It Works

  1. Import: Drop photos or a video into the app
  2. Align: Apple Photogrammetry computes camera positions automatically
  3. Train: Gaussian Splatting creates millions of tiny 3D ellipsoids that represent your scene
  4. Preview: Explore the 3D reconstruction from any angle in real time
  5. Export: Save in your preferred format or share as a web viewer

System Requirements

Frequently Asked Questions

What is 3D Gaussian Splatting?

A technique that reconstructs a real scene as millions of tiny 3D ellipsoids ("splats") from ordinary photos or video. The result is a photorealistic 3D scene you can explore from any angle in real time — a faster, sharper alternative to NeRF and traditional photogrammetry.

Do I need any other tools or a Python setup to use RadianceKit?

No. RadianceKit is a complete Gaussian Splatting workflow in a single Mac app. You import photos or video, align, train, edit and export — all inside the app. There is no command line, no Python environment and no external software to install.

Does RadianceKit run in the cloud or on my Mac?

Everything runs locally on your Mac. Training uses the Apple Silicon GPU through Metal — your photos and 3D scenes never leave your device. No account and no internet connection are required for processing.

What Mac do I need to run RadianceKit?

RadianceKit requires an Apple Silicon Mac (M1 or later) running macOS 26 Tahoe or later. 16 GB of RAM is recommended for comfortably training larger scenes.

How much does RadianceKit cost?

RadianceKit is free to download and includes a 3-day trial of all features. After the trial you can unlock the full version with a one-time in-app purchase of US$7.99 — no subscription and no upgrade fees. Prices are set per region, so your local App Store may show a different amount (8.99 € across the euro zone, for example).

Which file formats can I import?

RadianceKit imports three kinds of files. Source media for training a new splat: video (.mp4, .mov, .m4v, .avi) and photos (.jpg/.jpeg, .png, .heic, .tiff/.tif, .bmp). Existing splats you can open and view without training: .ply, .spz and .splat. And scenes & camera data: RadianceKit scene bundles (.radiancescene), COLMAP workspaces (a folder with sparse/ cameras plus an images folder) and .radiancecapture bundles from the iPhone companion app.

Can I import 360° footage (equirectangular, fisheye, Insta360)?

Yes. RadianceKit imports 360° photos and video natively: equirectangular, stereo 360° (top/bottom and side-by-side), cubemap, equi-angular cubemap (YouTube), fisheye 180/200° and partial panoramas. The projection is detected from the file's metadata, and you can set it manually in the import panel when that metadata was stripped on export. Each frame is then unwrapped into overlapping perspective views before alignment and training. Two limits are worth knowing. A single 360° photo cannot become a 3D scene — depth needs several camera positions, so record a walk-around video or shoot from multiple spots. And raw dual-fisheye containers (.insv, .insp, .360, .lrv) have to be stitched first: export them as equirectangular .jpg or .mp4 from Insta360 Studio, GoPro Player or the Ricoh Theta app, then import that file.

Which export formats does RadianceKit support?

You can export scenes as PLY, Compressed PLY, SPZ, glTF, .splat or SOG. RadianceKit can also create orbit videos and self-contained interactive web viewers you can share without any extra software.
