3D Gaussian Splatting or 360° virtual tour: which to choose for your project?
By Olivier Kerremans ·
The 360° virtual tour is a well-established technology, familiar to the public for several years. 3D Gaussian Splatting is something else entirely: a recent technological breakthrough, still rare on the market, that shakes up the rules and opens possibilities the 360° format simply cannot offer.
These are not two technologies sharing the market as equals. It is the arrival of a higher-generation tool in a space where the older technology has settled in comfortably. And like any breakthrough, it does not replace everything overnight: it answers what the older approach could not do.
This article helps you understand the real strengths of each, and choose according to your project.
The 360° virtual tour: well established, proven, accessible
Over the years, 360° has established itself as the consumer reference for virtual tours. It is built from panoramic photographs taken from fixed points with a specialised device on a tripod. These shots are then assembled and linked to create a point-to-point navigable path.
What it does well. It is a format the public recognises and understands: navigating from one point to another within a room is an immediately intuitive experience. Photographic quality on the captured angles is excellent: colours, materials and natural light are all rendered faithfully. Compatibility is maximal: older smartphones, limited connections, corporate tablets, nothing gets in the way. And in recent years, the spread of consumer 360° cameras has made this technology accessible to almost anyone for personal projects or experiments.
Its limits. Navigation happens by teleportation: you jump from one fixed point to another, without ever moving freely through the space in between. What the camera did not photograph does not exist. On large spaces or complex volumes, the number of capture points needed to cover the space properly rises quickly. Gamification and advanced interactions are not part of its native repertoire. And when the experience matters as much as the information, 360° reaches its limits quickly.
3D Gaussian Splatting: a breakthrough, not an evolution
3D Gaussian Splatting does not produce photos: it reconstructs a three-dimensional space from thousands of images captured in continuous motion. The result is a cloud of several million Gaussian points, each carrying information about position, orientation, size and colour. Rendered in real time in a browser, this cloud creates the illusion of moving freely through a photorealistic space, from any angle.
It is a recent technology, still little deployed on the market. In Switzerland, we are among the very first to offer it on professional projects.
What it does well. Navigation is free and continuous. No fixed points, no teleportation: you move through the space as you would walk, from every angle, including ones that were not planned during capture. On large volumes or architecturally complex spaces, the difference is immediately visible.
Gamification is native: guided paths, points of interest, audio or video content, interactive characters, everything can be built directly into the model. That is what our Story and Experience packages offer.
On capture time, 3DGS is just as fast, or faster than 360° on large spaces: a single sequence of continuous motion can cover an area that would require a great many points in 360°. In post-production, both technologies can be fast or take longer, depending on the level of experience sought.
Its limits. Files are heavier and rendering requires a device with a GPU capable of real-time 3D rendering. Very old or entry-level smartphones may struggle. Mastering 3DGS demands suitable equipment, specific software, a rigorous capture method and a level of technical experience that consumer 360° does not require. Finally, measurements extracted from a 3DGS model are usable in the vast majority of cases (estimating surfaces, distances, spatial organisation), but if millimetre surveys are needed for an architect or engineering firm, other tools are better suited.

When to choose the 360° virtual tour
360° remains a sound choice in specific situations.
A personal project, a hobby, an experiment. You have a 360° camera and want to test the format for your activity, your home or a side project. 360° is accessible, quick to produce, and requires no specialised skills.
Maximal compatibility is an absolute constraint. If your target audience uses old devices or very limited connections, 360° remains the most reliable choice. It works where 3DGS may run into difficulty.
A catalogue of standard properties with strict budget constraints. To quickly document a large number of identical properties at low cost, 360° is an effective tool.
When to choose 3D Gaussian Splatting
For the vast majority of professional projects, 3DGS delivers an experience that 360° cannot match.
The space is large or volumetrically complex. A monument, a castle, an industrial site, a campus: free navigation lets you explore volumes that no series of fixed points can do justice to.
You want a faithful archive. Before a renovation, before a structural transformation, before a closure: 3DGS captures the exact state of the space from every angle, navigable years later.
Gamification or interactions are part of your project. Guided path, interactive character, quiz, activation at an event or patient pathway in healthcare: this is 3DGS territory exclusively.
You want to stand out. In events, heritage, high-end real estate or healthcare, a free-navigation experience creates an immediate advantage over competitors who all present the same standardised formats.
3DGS is still rare on the market. That will not always be the case. Adopting this technology now means taking a lead that pays off quickly.
What neither one replaces
If you need precise technical drawings, BIM extraction or millimetre metric surveys for an architect or engineering firm, what you need is a point-cloud laser scanner. 3DGS produces measurements usable for most everyday purposes, but not for precision metrology.
Likewise, no virtual tour reproduces the sensory experience of a place. These technologies qualify interest and remove barriers remotely. They do not replace the physical visit for anyone who has decided to come.
The question to ask before choosing
What do you want the people who receive this link to do or feel?
If the answer is “get a quick idea of a standard space from their phone, whatever it is”, 360° may suffice.
If the answer is “explore freely, understand the volume, live an experience or move through a guided path”, 3DGS is the right answer. And in the vast majority of professional projects, it is this second answer that prevails.
360° established the market. 3DGS is now redefining it.

Frequently asked questions
Can 3D Gaussian Splatting replace a 360° virtual tour?
Yes for most professional projects, no in cases where compatibility with older devices is an absolute constraint. 3DGS brings free navigation and photorealistic rendering from every angle, whereas 360° offers teleportation between fixed points. For a standardised catalogue at reduced cost, 360° remains a sound choice.
Do you need a VR headset to view a 3D Gaussian Splatting model?
No. A 3DGS model is viewed in a standard web browser, on a computer, tablet or recent smartphone. No app, no installation, no headset. A GPU capable of real-time 3D rendering is required, which is the case for almost every device released in recent years.
Is 3DGS suitable for precise metric surveys?
For most everyday uses (estimating surfaces, distances, spatial organisation), yes. For millimetre-accurate surveys intended for an architect or engineering firm, a point-cloud laser scanner remains the reference. 3DGS and laser scanning can be combined on the same project.
How long does it take to produce a 3D Gaussian Splatting model?
On-site capture typically takes a few minutes to a few hours depending on the size of the location. The final model is delivered within 24 to 48 hours via a shareable web link, accessible from any recent device.
Is a 360° virtual tour more accessible technically than 3DGS?
Yes for production, a consumer 360° camera can suffice. For viewing, both technologies work with recent browsers. 3DGS requires a GPU capable of real-time 3D rendering, which rules out a few very old smartphones. 360° works everywhere.
