Zetta 3D has three engines that make Gaussian splats, and they differ in what they are trying to build: Zetta Splat captures what is in one picture; Zetta Splat 2 and Zetta Splat 2.1 build a whole world out from it that you can look around and move through.
| Zetta Splat | Zetta Splat 2 | Zetta Splat 2.1 | |
|---|---|---|---|
| Builds | An object or a place, as pictured | A world to look around in | A larger world, for big outdoor and indoor spaces |
| From one picture | Yes | Yes | Yes |
| From several pictures | No | Yes | Yes |
| From a video | No | Yes | Yes |
| Typical time | About four minutes | About five minutes | About five minutes |
| Delivered as | .splat | SPZ | SPZ |
Which engine should I use?
- Zetta Splat for a product, a prop or a single subject, where the picture is the whole story. With Object selected it can remove the background first, which is what makes a clean splat of a subject.
- Zetta Splat 2 for a room, a scene or a backdrop you want to move through.
- Zetta Splat 2.1 when the space is large — a warehouse, a street, a landscape.
What can a world be built from?
- One picture. Everything out of frame is inferred.
- Several pictures of the same space, each marked with the direction it faces — right, back, left, the diagonals or any angle. Up to four, or eight when they are all of the same space. Directions you did not photograph can be drawn from the main picture.
- A video of the space, up to 100 MB as MP4, MOV or WebM. See filming a video for a splat.
- A prompt. The prompt becomes a picture first, which you check before the splat is made. For a world you can choose its ratio and resolution, and the world engines also read the prompt as a description of the scene.
How do I look at a splat?
In the browser. Objects orbit; worlds can be flown through — drag to orbit, right-drag to look, WASD to move — with full screen and a quality setting. A world opens in a standard or a high-quality version, and only the one you choose downloads.
What can I do with a world afterwards?
From Inspect, a world exports as splats (PLY), as a mesh (GLB) — textured or with vertex colours — or as a collider mesh (GLB) for physics. The exported mesh is an ordinary model: retopology, texturing and the other mesh tools run on it. They do not run on the splat itself.
Who can use it?
Gaussian splats come with a paid plan, and Generate Splat is in early access — request access from the Generate Splat tab and the team switches it on for your account.
