3D Gaussian Splatting (3DGS) of real assets, ready to explore in the browser.
3D Gaussian Splatting (3DGS) reconstructs a real space from photos or video and represents it as millions of gaussians with colour and transparency, so it looks almost like a photograph and can be explored in real time. We carry out the capture on site, process the splat and deliver it published in VisionHub, our web viewer, so heritage bodies, architects, industry and construction can share it with a link. Almost nobody in Spain offers this commercially yet — and for a client reviewing an asset remotely, it is the difference between reading a report and seeing the place. We capture in Spain and across Europe.
When visual precision matters too.
Gaussian Splatting (3DGS) is a recent technique that reconstructs a space from photographs or video and displays it photorealistically and navigably in the browser, close to being there. A point cloud is unbeatable for measuring; Gaussian Splatting is unbeatable for seeing and explaining. Together they give you a digital twin that is both accurate and easy to show to somebody who is not an engineer.
Industry
Understanding facilities
Natural visualisation of plants, plant rooms, tanks and service routes, where a navigable photograph removes ambiguity.
Construction
Real state, communicable
Monitoring, presentation and visual sign-off of spaces before, during or after an intervention.
3DGS to see; LIDAR to measure.
The right approach is to choose the data by the decision: LIDAR and BIM for metric accuracy, Gaussian Splatting for visual experience and spatial understanding.
When to use Gaussian Splatting
- Presenting heritage, architecture or industrial spaces.
- Web walkthroughs for clients, authorities or non-technical teams.
- Visual context for interventions and existing assets.
- As the photorealistic layer of a digital twin.
When to combine it with LIDAR
- Where reliable measurements and technical documentation are needed.
- Where as-built BIM modelling or derived drawings will follow.
- Where the asset has complex services or critical geometry.
- Where the visualisation has to be checked against metric reality.
Gaussian Splatting versus traditional photogrammetry.
Traditional photogrammetry produces point clouds from imagery, from which digital terrain models (DTM), digital surface models (DSM), orthophotos, meshes and metric point clouds are derived — accurate, but without the hyper-realistic quality good visualisation needs. That is where Gaussian Splatting wins: you can move through the scene in high definition with realistic lighting, though you cannot take measurements from it. The two are combined to hold metric data and visual experience at the same time.
Traditional photogrammetry
- Produces point clouds from photography.
- Derives DTM, DSM, orthophotos, meshes and point clouds.
- Metric accuracy for measurement and modelling.
- No hyper-realistic quality for visualisation.
Gaussian Splatting (3DGS)
- Does not measure: renders volumetric gaussians with realistic lighting.
- High-definition navigation at near-photographic quality.
- Built for visualisation and communication, not measurement.
- Smooth movement in the browser, nothing to install.
They are not substitutes: photogrammetry or LIDAR supply the metric data, Gaussian Splatting the hyper-realistic visual experience. Together they cover measurement and communication at once.
SuperSplat, Postshot and Gaussian Splatting viewers.
Anyone researching 3DGS soon runs into these names. They are different tools for different stages of the work, and it helps to know what each one does before deciding whether to do it in-house or commission it.
Delivery
VisionHub
This is where we deliver every project. VisionHub opens the splat in PLY or SPZ format straight in the browser and makes it ready to share with a link, alongside the point cloud and the BIM model if the project has them. Whoever receives it installs nothing and does not need to know what a splat is.
Editing
SuperSplat
SuperSplat is a free, open-source web editor developed by PlayCanvas. It is used to inspect, clean up, crop and optimise a Gaussian splat that has already been generated. It does not train the model from photos: it works on the finished splat.
Training
Postshot
Postshot, by Jawset, is desktop software that trains a Gaussian Splatting model from photos or video. It runs on Windows with an NVIDIA GPU, has a free version for non-commercial use and requires a paid licence for professional use and for exporting the splat.
The software is the easy part. What decides whether a Gaussian splat looks good is the capture: coverage, light, overlap and route. That is why our service starts on site and ends with the splat processed, reviewed and published in VisionHub. If you also need to compare viewers for BIM models, our guide to BIM viewers covers it.
Capture designed for the web.
A good 3DGS result depends on planning: route, lighting, coverage, overlap, critical areas and the final visualisation objective.
01
Visual scope
We define the visual objective, the key scenes and the areas that need maximum detail.
02
Capture plan
We design routes and paths, and resolve constraints of light, access and overlap between shots.
03
Site capture
We record the asset with photography and video, supported by a point cloud where the scene needs it.
04
3DGS processing
We generate the photorealistic model and review visual continuity, navigation and critical viewpoints.
05
Web delivery
We prepare the result for a viewer or share it as a navigable experience.
Questions about Gaussian Splatting.
What is the difference between a point cloud and a Gaussian splat?
A point cloud stores millions of points with their exact position in space: every point holds real coordinates, so distances, heights and areas can be measured — but up close you see gaps, with no texture and no highlights. Gaussian Splatting turns each point into a soft blob of colour with shape and transparency: volume, reflections and materials appear, and the scene looks almost like a photo, though you can no longer measure on it. In one project both are used: the point cloud to work with, the Gaussian splat to show.
What is Gaussian Splatting?
Gaussian Splatting (3DGS) is a 3D reconstruction technique that represents a scene as millions of volumetric gaussians, producing photorealistic results rendered in real time in a web viewer or in virtual reality.
How is a Gaussian Splatting model of a building produced?
In five stages: define the visual objective and the key areas, plan the capture route (light, access, overlap), capture photography and video on site with point cloud support where the scene needs it, process the 3DGS model checking continuity and navigation, and deliver it embedded in a navigable web viewer.
How does it differ from photogrammetry or LIDAR?
LIDAR point clouds and photogrammetry exist to measure accurately; Gaussian Splatting exists to show and explain a space at photorealistic quality. They combine well: LIDAR to measure, 3DGS to explain.
How is the result viewed?
The model is explored directly in a browser, with no software to install and free movement through the scene, and can be shared by link with clients, public authorities or non-technical stakeholders anywhere in the world.
Does Gaussian Splatting replace traditional photogrammetry?
No. Traditional photogrammetry produces point clouds from imagery, from which DTMs, DSMs, orthophotos, meshes and metric point clouds are derived — accurate, but without hyper-realistic visual quality. Gaussian Splatting does not measure: it renders the scene in high definition with realistic lighting, for navigation and presentation. The two are combined to get the best of both.
How do you open a Gaussian Splatting file?
A Gaussian splat is usually saved as a PLY file, or as SPZ when compressed. It needs a viewer that can render gaussians; a mesh or point cloud viewer will not display it properly. We deliver it already published in VisionHub, which opens PLY and SPZ in the browser and lets you share it with a link. For editing or cleaning up the splat there are tools such as SuperSplat.
What is the difference between 3DGS and photogrammetry?
Both start from photographs, but they produce different results. Photogrammetry computes measurable geometry (point cloud, mesh, orthophoto or DTM) and its visual quality is limited. 3DGS optimises millions of gaussians to reproduce how the scene looks from any viewpoint, including reflections and transparency, but it is not designed for measuring. One is for working with dimensions; the other is for showing the space.
