Nucleus4D Technology: Revolutionary 3D Gaussian Splatting
Nucleus4D technology leverages cutting-edge 3D Gaussian Splatting to transform physical spaces into digital twins. This technique exploded in popularity in 2023, when researchers from Inria proposed 3D Gaussian splatting that offers real-time radiance field rendering. The approach represents a quantum leap beyond traditional photogrammetry and NeRF (Neural Radiance Fields) methods.
How does 3D Gaussian Splatting real estate technology work? Gaussian Splatting represents a 3D scene as millions of particles shaped like ellipsoids, with each 3D gaussian having unique parameters such as 3D position, orientation, 3D scale, opacity, and view-dependent color. This creates photorealistic digital environments that both humans and machines can interpret.
Unlike legacy virtual tour solutions, Nucleus transforms real-world spaces into high-fidelity, interactive digital twins using advanced spatial capture, 3D Gaussian splatting (3DGS), and AI-driven reconstruction. The platform consolidates previously fragmented workflows. What used to require multiple people, tools, and pipelines can now be generated from a single on-site capture: immersive self-guided tours, live virtual showings, cinematic video, floor plans, measurements, and structured spatial data.
The competitive advantage runs deeper than efficiency. A 3D model generated using 3D Gaussian splatting is highly photorealistic, accurately captures geometry, and has the ability to capture larger scenes with negligible artifacts. This technical superiority positions digitizing built world startups like Nucleus4D ahead of competitors using older reconstruction methods.
Real-world applications extend across industries. Since launch in Q3 2025, Nucleus has showcased more than 25 million square feet of residential, commercial, and hospitality space on its platform, demonstrating rapid market adoption. Furthermore, Nucleus is the first 3DGS company to receive approval to list immersive experiences within a leading online real estate listing service and marketplace.
