About

What is OpenSplat?

OpenSplat is a free and open-source C++ implementation of 3D Gaussian splatting, designed for portability, efficiency, and speed. It can run on Windows, Mac, and Linux, with support for NVIDIA, AMD, and Apple (Metal) GPUs, as well as CPU-only operation (though significantly slower). The tool takes camera poses and sparse points from formats like COLMAP, OpenSfM, ODM, or nerfstudio projects to compute scene files (.ply or .splat). These generated files can then be imported into other software for viewing, editing, and rendering. OpenSplat is licensed under AGPLv3, allowing and encouraging commercial use.

Best used for

Ideal for developers and content creators who need to generate 3D scene files from various input data formats, process them efficiently with CPU or GPU, and prepare them for further viewing or editing. Especially valuable for those working with 3D Gaussian splatting technology across different operating systems.

FAQs

What input formats does OpenSplat support for 3D data?

OpenSplat can process camera poses and sparse points from several popular formats, including COLMAP, OpenSfM, ODM, and nerfstudio projects. It requires sparse points to be included in the project for successful processing, as random initialization is not currently supported.

Can OpenSplat be used for commercial projects?

Yes, OpenSplat is licensed under the AGPLv3, which explicitly allows and encourages commercial use. This makes it a suitable option for businesses and professionals looking to integrate 3D Gaussian splatting into their commercial workflows.

What are the hardware requirements for running OpenSplat?

While OpenSplat can run entirely on a CPU, a graphics card is highly recommended for optimal performance, as CPU-only operation is significantly slower. It supports NVIDIA, AMD, and Apple (Metal) GPUs, with specific build instructions provided for each.
