PLEDGE: Progressive Lossy Error-Bounded Compression of 3D Gaussian Splatting

PLEDGE is a training-free, progressive, error-bounded codec that translates four user-declared tolerances into per-primitive quantization bounds: screen-space position, footprint deformation due to rotation and scale, view-dependent color, and opacity.
