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

Existing 3D Gaussian Splatting (3DGS) codecs report reconstruction quality after compression, and give users little control over the distortion of individual primitives. We present PLEDGE, a training-free, progressive, error-bounded codec that translates four user-declared tolerances into per-primitive quantization bou...

FaCTz: Fast Critical-Point and Topology-Aware GPU Compression for Scientific Vector Fields

FaCTz is presented, the first GPU-based error-bounded lossy compressor that guarantees critical-point preservation and provides a block-wise mode optimized for throughput and a speculative per-point mode optimized for compression ratio.
