CityGaussian

Why we included this project

Most Gaussian Splatting examples stick to a single object or a small room, but this project is aimed at outdoor and urban scenes at city scale. It combines two peer-reviewed methods, one for real-time rendering of large scenes and a follow-up that improves geometric accuracy, into a single pipeline. Multi-GPU reconstruction keeps memory use controllable, so you don't need a massive cluster to process big captures, and mesh extraction is available when you need geometry-aware output. The reference implementations are useful for reproducing the papers and for prototyping photorealistic digital twins of real environments. The main branch has been rebased onto Gaussian Lightning and includes support for VGGT-X, which makes it easier to integrate into an existing workflow.
