RadianceKit

Key Features

• •Native GPU Training on Apple Silicon: RadianceKit uses Apple's Metal API to perform 3D Gaussian splatting training directly on the GPU of M1–M4 Macs. This eliminates the need for cloud GPUs, ensures data privacy, and delivers fast photorealistic reconstructions in minutes.
• •Simple and Expert Mode: Simple Mode guides beginners through a three-step process: import media, press Start, and receive a 3D scene. Expert Mode provides a three-panel layout with project navigator, interactive viewport, and inspector for training parameters, loss curves, and export settings.
• •Six Export Formats: Export scenes as PLY, Compressed PLY, SPZ, glTF, .splat, or SOG. Additionally, generate orbit videos or self-contained web viewers that can be shared without any extra software, ensuring compatibility with various workflows.
• •Interactive Gaussian Editor: Select and delete unwanted regions directly in the 3D viewport using a brush tool. Remove floating artifacts or stray splats with precision, and use undo for non-destructive edits to fine-tune reconstructions, giving users direct control over final scene quality.
• •Automatic Camera Alignment with Apple Photogrammetry: RadianceKit uses Apple's Photogrammetry framework to automatically compute camera positions from imported photos or video. This eliminates manual alignment steps and prepares the data for Gaussian splatting training, producing an accurate sparse point cloud.
• •Live Training Metrics: During training, Expert Mode displays live loss curves and metrics in the inspector panel. Users can monitor the progress of the reconstruction in real time, making it easy to adjust parameters or stop training when optimal quality is achieved.

Use Cases

• •Product Photography: A photographer captures a flower bouquet with a standard camera, imports the photos into RadianceKit, and within minutes exports a photorealistic 3D model for an e-commerce website. The outcome is a printable or embeddable asset that enhances online product listings.
• •Cultural Heritage Digitization: A museum uses RadianceKit to digitize a marble sculpture such as Michelangelo's David. The resulting 3D Gaussian splat can be explored interactively in a web viewer, enabling virtual access for remote audiences without physical handling.
• •Architectural Scanning: An architect photographs a room interior and uses RadianceKit to create a digital twin. The exported glTF model can be imported into BIM software for renovation planning, providing an accurate spatial reference.
• •Game Asset Creation: A game developer captures real-world objects like a plush toy or a statue, processes them in RadianceKit, and exports as .splat or PLY to use as in-game assets. The photorealistic quality reduces manual modeling time.
• •Education and Research: An educator demonstrates 3D reconstruction by scanning a complex object in class using a Mac and RadianceKit. Students can view the reconstruction in real time, learning about photogrammetry and splatting techniques.
• •Real Estate Virtual Tours: A real estate agent scans a property's exterior with video, processes it in RadianceKit, and shares a web viewer link with potential buyers for an immersive preview.

Who is this for?

RadianceKit is tailored for 3D artists, photographers, game developers, architects, and cultural heritage professionals who need on-device photorealistic 3D reconstruction. It is also suitable for Mac power users who prefer local processing over cloud services. Educators and researchers in computer graphics and computer vision will find it accessible for demonstrating 3D Gaussian splatting concepts. The app's simple mode lowers the barrier for hobbyists and content creators seeking quick 3D captures, while expert mode satisfies the demands of scanning technicians and digital preservationists. No Python or command-line knowledge is required, making it ideal for professionals who want a tool that works out of the box on their Apple Silicon Mac.
