How the Moor is Captured

Each scene is recorded using aerial photogrammetry — structured passes at multiple altitudes and angles, producing thousands of overlapping frames across every face of the site.

3D Gaussian Splatting converts this imagery into a cloud of oriented Gaussians, each encoding position, colour, opacity and covariance. The result is a real-time radiance field you can navigate freely — not a frozen mesh, not a video.

Models are optimised for web delivery and explored directly in your browser. No plugin required.

01

Aerial Capture

Precision camera equipment — structured orbital and grid passes at altitude, with close-quarters detail work where required

02

SfM Processing

COLMAP structure-from-motion to establish camera poses and a sparse point cloud from every frame

03

3DGS Training

Gaussian Splatting optimisation — 30k iterations producing a dense splat field

04

Web Delivery

gsplat.js WebGL renderer — real-time sorting and rendering in-browser, no plugin
