3D Gaussian Splatting capture: a practical guide.

The short answer: 3D Gaussian Splatting (3DGS) turns a capture of a real space into a photorealistic 3D scene that renders smoothly in an ordinary browser. In Singapore you can produce 3DGS scenes by renting XGRIDS equipment — the Lixel K2 when you also need measurable point cloud data, or the PortalCam for purely visual capture — and processing through the LCC CyberColor workflow. Weekly K2 rental is from S$2,300 (dry, subject to approval).

What 3DGS actually is

Instead of triangles and textures, a 3DGS scene is millions of tiny oriented, semi-transparent splats, each carrying colour and opacity. Rendered together they reproduce a space with the soft realism of photographs — reflections, foliage, and fine detail included — while remaining fully navigable in 3D. It is the first reality-capture format that looks right to non-technical stakeholders and runs in a browser tab.

What it is good for

• Real estate and venues — walkable property and event-space scenes for listings and proposals.
• Media, XR, and virtual production — real locations as photorealistic environment assets.
• Heritage — appearance-faithful records of culturally significant spaces.
• Digital twins — the human-friendly visual layer over technical capture data.
• Stakeholder communication — anyone can navigate a 3DGS scene; nobody enjoys navigating a raw point cloud.

What it is not

3DGS is not a measurement format. It is built to be seen, not dimensioned — measurement and modelling stay in point cloud territory. This is exactly why the Lixel K2 workflow is attractive: one walk produces both the technical point cloud and the 3DGS scene, depending on processing.

Device choice: K2 or PortalCam

Rent the Lixel K2 when the project needs geometry and visuals — renovation plus marketing, twin data plus walkthrough. Rent the PortalCam (enquiry-based) when the output is purely visual and capture simplicity matters most. Processing runs through LCC CyberColor in both cases.

Capture technique for good splats

• Light the space as you want it remembered — 3DGS faithfully reproduces whatever lighting you give it.
• Move steadily and cover viewpoints generously; the reconstruction can only know what the capture saw.
• Mind highly dynamic scenes — moving people and vehicles become artefacts.
• Plan loop closures as you would for any SLAM capture when using the K2.

Singapore considerations

• Venue and showflat capture windows are short — walkthrough capture fits them.
• Tropical light changes fast; capture a space in one session for consistent appearance.
• Per-property rental economics beat platform subscriptions for occasional use — see K2 vs Matterport.

Limitations, honestly

Quality depends on capture coverage, lighting, and processing; mirrors and glass remain hard; very large scenes need capture planning. And 3DGS complements rather than replaces point clouds — teams that need both should capture with the K2, not chase splats alone.
