SPLAT

Gaussian splatting (3DGS) is a 3D scene representation method that has gained traction in recent years. It uses millions of 3D Gaussian ellipsoids to achieve photorealistic novel view synthesis on consumer GPUs, rendering in real time at 100+ FPS. It is widely used in next-generation scene reconstruction and digital human applications following NeRF.

SPLAT is the native container format for Gaussian splatting. It is fundamentally different from mesh-based systems: it has no editable topology and cannot be directly used for 3D printing or traditional modeling workflows. The current ecosystem also includes compressed variants such as SPZ, KSPLAT, and SOG, which accelerate web loading.
