Upload your first Gaussian Splat scene

Kroscloud turns a Gaussian Splatting capture — a photoreal scan made with a phone app or a desktop program — into a fast, interactive web scene that runs in any modern browser. Once it's uploaded you can add points of interest with audio, anchor it to real-world GPS, let visitors measure it (with a reference mesh), protect it with a password, and then share it with a single link or embed it in your own website. This guide takes you from your splat file to your first live scene.

Splat file formats you can upload

Kroscloud accepts the five common splat file formats. Upload whichever your tool exports — Kroscloud optimizes every upload automatically, and your original file is archived untouched at full quality, so improved delivery formats can be produced later without a re-upload.

Size & performance

Don't worry about making the file small for your visitors — that part is automatic. Kroscloud compresses every upload (~80% smaller in our tests) and prepares it two ways: a full-detail version that shows every splat you uploaded, loaded once and crisp from the first frame — used for most scenes — and a streaming version for very large scenes, lighter devices and browsers without WebGPU, which starts quickly and sharpens as the visitor explores. The viewer picks the right one for each visitor's device automatically — see Full detail and streaming for how it decides and which splat count to aim for if your visitors use phones and tablets.

Upload your splat scene, step by step

1. Start a new splat scene

Sign in and open My board. Click Create new scene, then choose 3D Splat Scene to open the splat upload page.

2. Choose your file

Select your splat file — or drag and drop it onto the page. Kroscloud reads the file header and shows what it found on the spot: the file size, the splat count and whether it fits your plan, for every supported format. There's no 3D preview at this step; you'll see your scene rendered right after processing.

3. Name it and save

Give your scene a title (you can change it any time), an optional description, choose whether it's private, and pick a folder. Click Save — the upload finishes and you're back on My board immediately.

4. Let Kroscloud optimize it

Your new scene appears on the board as a Processing tile. In the background Kroscloud validates the file, compresses it, prepares it for streaming, renders a thumbnail and frames an opening camera view. The tile switches to ready by itself — small scenes take a few minutes, the largest captures with tens of millions of splats around half an hour. No need to keep the page open.

5. Make it interactive

Open the finished scene in the editor. The first time, Kroscloud asks you to confirm the scene's orientation (flip it upright if the capture came in sideways) — do this first, before adding points. Then bring it to life: add points of interest (including 360° panoramic points that teleport visitors into a panorama and back), attach an audio guide, anchor it to GPS coordinates, and set the starting camera view.

Add measurement, height profiles and contour lines

A splat has no solid surface of its own, so measuring on it needs a reference mesh: a .glb of the same scene that Kroscloud keeps invisible and uses only as the surface the tools measure on. Once it's uploaded, visitors get the same distances, height profiles and contour lines as on any Kroscloud 3D model scene. Uploading the reference mesh needs a Premium plan or higher (it also makes clicks land exactly on the surface); measurement, height profiles and contour lines are Business features. The steps below are the quick version; Collider mesh explains which tools give you a mesh that lines up, how to prepare it, and what changes for your visitors.

1. Export a mesh from the same project

The mesh must come from the same project or capture as your splat so both share position and scale — export it from the same RealityScan or 3DF Zephyr project as the splat, or export a mesh of the same capture from Scaniverse, Polycam or KIRI Engine (convert it to .glb if the app exports another format). Decimate it heavily and strip textures, then export as .glb — in metres, uncompressed.

2. Upload it in the Collider mesh menu

Open your splat scene in the editor and choose Collider mesh. Click Upload collider mesh (.glb) and pick your file. While the menu is open the mesh is drawn as a wireframe over the splat, so you can check that they line up (it disappears again when you close the menu). If the mesh comes in rotated, turn it with the rotate buttons (90° steps about X, Y or Z) — this fixes the usual axis mismatch between tools without a re-export. You can replace or download the mesh from the same menu at any time.

3. Switch Measurement on

Open the Measurement menu and turn measurement on. Set Model Unit to the unit your mesh was exported in — metres for most photogrammetry and capture tools. If the scene is georeferenced with all three GPS points, you can enable Use GPS distances to scale measurements from the georeference instead. Visitors can now measure distances, read height profiles and add contour lines on your splat.

What you can build next

Uploading the splat is just the start. The interactive presentation features that power Kroscloud's 3D model scenes work directly on your capture:

• Points of interest with audio — clickable hotspots with text, images, YouTube videos or a spoken audio guide, placed by clicking directly on the splat.
• Panoramic points — drop visitors into a 360° view and back into the splat, combining drone-scale capture with ground-level detail.
• Georeferencing — on-site visitors see their live GPS position inside your capture.
• Measurement, height profiles & contour lines — upload a reference mesh and visitors measure on the splat as on a 3D model scene (Business).
• Protected scenes — lock client work behind a password or secret access links.
• Scene analytics — see views, engaged time and which points visitors opened, cookie-free.

When it's ready, share or embed your scene anywhere — the embed works like a YouTube video: one iframe snippet on your own website.
