is a technique for compressing 3D Gaussian Splatting (3DGS) scenes
it reorganizes thee high-dimensional attributes into locally smooth 2D grids, allowing standard image compression techniques to achieve high compression ratios
it uses a Parallel Linear Assignment Sorting (PLAS) algorithm to sort Gaussian splat properties, grouping similar attributes spatially to create structured 2D “attribute images” from the initial noisy data
