What it is
A way to represent a captured scene with many small colored Gaussian primitives.
Gaussian Splatting Basics
What is Gaussian Splatting?
Gaussian splatting is a way to turn real-world capture into a photorealistic 3D scene. It is often called 3DGS, Gaussian splats, gsplats, or 3D splatting. The useful result is a scene people can open, move through, and understand in a viewer or published tour.
Capture
Video, 360 footage, photos, drone media
Reconstruct
Camera poses plus optimized splats
Publish
Viewer, guided tour, embed, CTA
Short answer
A captured scene, rendered from splats
The plain-language version: Gaussian splatting uses captured views to build a 3D scene made of many small colored splats. That scene can then be opened in software, reviewed, optimized, and published as a tour.
Why people use it
It can make real spaces feel more photographic and walkable than flat images.
What still matters
Capture quality, file size, mobile performance, and the published viewer experience.
Terminology
Gaussian splatting, 3DGS, Gaussian splats, gsplats, and 3D splatting
Search results use several names for the same family of scene reconstruction and rendering workflows. These terms usually differ by audience, not by a completely separate product category.
| Term | What it usually means |
|---|---|
| Gaussian splatting | The broad technique for reconstructing and rendering a 3D scene with many small Gaussian primitives. |
| 3DGS | Short for 3D Gaussian Splatting. Researchers, developers, and technical tools often use this shorthand. |
| Gaussian splats | The visible scene elements or final scene people open in a viewer, editor, or published tour. |
| gsplats | A shorter informal term for Gaussian splats, often used by creators and technical communities. |
| 3D splatting | A looser search phrase that usually points to the same category of splat-based 3D scene rendering. |
Workflow
How Gaussian splatting works in practice
The technical pipeline matters, but the finished experience matters more. A strong workflow starts with reliable capture and ends with a scene someone can actually use.
01
Capture
Record overlapping video, 360 footage, photos, drone media, or other source images from the space.
02
Camera poses
Solve where each camera frame was taken so the reconstruction has a reliable spatial path.
03
Gaussian optimization
Train many colored Gaussian primitives until the scene matches the source views closely enough to render.
04
Rendering
Open the result in a viewer that can draw the splats quickly as the visitor moves through the scene.
05
Review
Check the first view, confusing areas, floaters, file size, mobile load, and whether navigation is clear.
06
Publishing
Turn the raw scene into a browser link, embed, guided tour, hotspot experience, or client handoff.
Comparison
Gaussian splatting compared with other 3D workflows
No 3D method wins every job. Choose based on the final deliverable: a browser walkthrough, a measured model, a technical inspection asset, a game-ready mesh, or a quick panorama tour.
| Compared with | Where the other workflow is strong | Where splats fit |
|---|---|---|
| NeRF | Strong for novel-view synthesis and research pipelines. | Gaussian splatting often renders faster in real-time viewers and can be easier to inspect as a scene asset. |
| Photogrammetry | Strong when a mesh, texture, or measurement-focused model is needed. | Gaussian splatting is often stronger for photorealistic walkthroughs, but it is not a replacement for every mesh workflow. |
| Point clouds | Useful for survey, inspection, and sparse or dense spatial records. | Gaussian splats usually look more photographic, while point clouds can be clearer for technical review. |
| Meshes | Better when geometry must be edited, measured, exported, or used in conventional 3D tools. | Splats can look more realistic from captured views, but geometry is less direct. |
| 360 tours | Fast to capture and simple to understand with fixed panorama positions. | Gaussian splatting adds depth and parallax, but it needs stronger capture and performance checks. |
Use cases
Where Gaussian splatting is useful
Gaussian splatting works best when photorealistic spatial viewing helps someone understand a real place, object, or route before they visit, inspect, or present it.
Real estate
Show layout, room order, finish details, views, and inquiry paths in a guided property tour.
Hospitality and venues
Help guests inspect rooms, amenities, event layouts, entrances, and arrival context.
Tourism and campuses
Publish walkable routes for destinations, schools, public spaces, and visitor centers.
Heritage and culture
Preserve and share captured spaces with labels, guided stops, and public access links.
Construction and infrastructure
Present site context, stakeholder walkthroughs, progress updates, and access notes.
VFX and creative
Use splats for captured environments, reference scenes, previz, and creative experiments.
Limitations
What to check before relying on a splat
A Gaussian splat can look impressive and still fail as a deliverable if capture, file size, navigation, or mobile viewing is weak.
Capture quality
- Poor overlap, fast movement, low light, reflective surfaces, and missed angles can create blur or gaps.
- Moving people, cars, fans, screens, and water can leave artifacts in the reconstructed scene.
Performance
- Large splat files can load slowly, especially on mobile devices or weak networks.
- A viewer may need level-of-detail streaming, compression, or scene cleanup for public pages.
Geometry and measurement
- Splats are usually not the best output when exact geometry, CAD workflows, or measurement is the main need.
- Use mesh, scan, survey, or point-cloud workflows when accuracy requirements are strict.
Formats and tools
Files, viewers, editors, and publishing
Gaussian splatting software can mean several things: generation, file viewing, editing, compression, engine integration, cloud hosting, or tour publishing.
.ply, .splat, .spz, WebGL
Viewer
Open the scene, test movement, and check desktop and mobile load.
crop, cleanup, orientation
Editor
Remove distracting areas, set the first view, and prepare the scene for sharing.
video to splat, 360 to 3DGS
Generator
Turn source media into a Gaussian splat with a cloud or local pipeline.
waypoints, hotspots, embeds, CTAs
Tour publisher
Make the scene useful as a browser link, listing page embed, or client handoff.
Real Horizons
From raw capture to a guided browser tour
Real Horizons focuses on the practical layer around Gaussian splatting: source upload, cloud generation, scene review, guided context, browser publishing, embeds, analytics, and visitor actions.
What Spatial Studio adds after the splat
- Publish a hosted tour instead of sending a raw file.
- Set the opening view, waypoints, hotspots, labels, and CTA path.
- Share the experience with a browser link, website embed, QR code, or campaign page.
- Track analytics for tour opens, hotspot clicks, source campaigns, and visitor actions.

FAQ
Gaussian splatting FAQ
Common questions behind searches for Gaussian splatting, 3DGS, Gaussian splats, gsplats, software, viewers, and tours.
What is Gaussian splatting?
Gaussian splatting is a 3D reconstruction and rendering method that represents a scene with many small colored Gaussian primitives. The result can look like a photorealistic space that people can move through in a browser or viewer.
What does 3DGS mean?
3DGS means 3D Gaussian Splatting. It is a common shorthand for the technique, especially in papers, developer tools, viewers, and technical communities.
Are Gaussian splats and gsplats the same thing?
Usually, yes. Gaussian splats and gsplats are informal names for splat-based 3D scenes or the primitives that make those scenes visible.
Is Gaussian splatting better than NeRF or photogrammetry?
It depends on the job. Gaussian splatting is often useful for photorealistic walkthroughs and real-time viewing. NeRFs, photogrammetry, meshes, point clouds, and 360 tours can be better for other needs such as measurement, geometry editing, or very fast capture.
What software opens Gaussian splats?
Gaussian splats can be opened in dedicated viewers, editors, research tools, game-engine integrations, and web-based platforms. The right software depends on whether you need to inspect a file, edit a scene, generate a splat, or publish a guided tour.
Can Gaussian splatting be used for real estate and virtual tours?
Yes. It is useful when layout, depth, room connection, site context, or visitor orientation matters. A good real estate workflow still needs careful capture, mobile testing, and guided context around the raw scene.
