OOOSplat: 3D Generator — What It Does and What You Need to Run It

OOOSplat is an open-source local 3D generator from ooolab. It turns ordinary videos or image sequences shot around an object into 3D Gaussian Splatting. The entire process runs on the user's computer, without uploading source files to the cloud.

What it does

As described by the author, the app works in "one-button" mode: the user selects the source material, the project folder and the quality level, after which OOOSplat prepares the frames, recovers camera positions, trains the model and publishes the result in PLY format. The finished model can be viewed, adjusted and exported.

The authors note that the Windows and macOS on Apple Silicon builds include FFmpeg, FFprobe, COLMAP and Brush. For Linux, support is stated only as an alpha version for Ubuntu 24.04 LTS x86_64.

The interface is built on React and talks to a local Rust backend via Tauri. According to the developers, no remote services or localhost API are needed: computation runs on the computer's own CPU and GPU.

What you need to run it

The platform, as described by the author, is Apple Silicon. Builds for Windows and an alpha version for Ubuntu 24.04 LTS x86_64 are also mentioned. The authors do not specify memory requirements or specific CPU or GPU models.

The code is open source and distributed under the Apache-2.0 license. It permits using, modifying and distributing the program, including as part of other products, provided the license text is retained and changes are indicated.

The repository is available at github.com/ooolabdev/ooosplat. The primary language of the code is Rust. The last change in the repository is dated September 13, 2026; it was created on August 15, 2026.

Who it suits

The tool is aimed at those who need to quickly get a 3D scene from video footage or a set of photos without manually configuring a pipeline. Local processing will be useful when working with material that cannot be uploaded to cloud services.

OOOSplat will be less convenient for those working on Linux distributions other than Ubuntu 24.04 LTS x86_64, or on computers without supported platforms. It is also worth noting that export is stated only in PLY — additional conversion may be needed to pass the result to other editors.

OOOSplat covers the basic scenario of "video around an object — a finished Gaussian model" and does so without cloud computing. For tasks that require other export formats or operation on other operating systems, the app's capabilities may not be enough.
