3DGS represents a scene as millions of tiny, colored ellipsoidal "splats" floating in 3D space — each carrying position, color, opacity, and view-dependent appearance for photorealistic real-time rendering.

Core Reconstruction Technologies
Understand the foundational 3D reconstruction methods behind Get3D — including 3D Gaussian Splatting, air-ground fusion, SLAM, and oblique photogrammetry. These technologies form the backbone of modern reality capture.

3DGS vs. Traditional Photogrammetry
A head-to-head technical comparison across seven dimensions — rendering quality, processing speed, data size, interactivity, and more — to help you choose the right tool for the task.

3DGS for City-Scale Digital Twins
How 3D Gaussian Splatting addresses the multi-scale demands of city-scale digital twins — from regional overview (LOD 1) to architectural precision (LOD 4) across hundreds of square kilometers.
Air-Ground Fusion

What is Air-Ground Fusion?
Get3D's foundational technology enabling seamless integration of aerial and ground-level data — an end-to-end solution combining data acquisition, automated fusion, and intelligent processing.
02
Get3D Air-Ground Toolkit
The complete Get3D ecosystem — Mapper, R200 scanner, 5-in-1 camera, and Farm Lite — covering all four stages of Air-Ground Fusion from aerial capture to ground-level scanning without integration overhead.
03
Air-Ground Fusion Advantages
Complete and high-fidelity 3D models with measurement-grade accuracy — how air-ground fusion overcomes the limitations of single-source capture through seamless integration of aerial and ground data.
05
What is SLAM and Why It Matters?
SLAM (Simultaneous Localization and Mapping) allows a moving sensor to build a map while tracking its own position in real time — making handheld, backpack, and vehicle-mounted laser scanning practical.
06
What is Oblique Photogrammetry?
The aerial foundation of city-scale 3D — capturing imagery from multiple angles simultaneously (one nadir + four oblique views) to reconstruct complete 3D models of buildings and urban infrastructure.
