4D scene reconstruction aims to recover the evolving geometry, appearance, and motion of dynamic environments from visual observations. Despite substantial progress in neural scene representations, reconstructing dynamic scenes remains challenging due to non-rigid motion, occlusions, temporal inconsistencies, and the t...

SCULPT iteratively applies a joint split predictor to generate one extracted part together with the remaining object, and demonstrates state-of-the-art geometry on PartObjaverse while preserving strong complete-object reconstruction after part assembly.

GrainGS is a dynamic Gaussian framework that combines a hierarchical anchor scaffold with per-Gaussian deformation that achieves high reconstruction quality, real-time novel view synthesis, and compact storage.
Experiments show that ProxyUp outperforms strong video editing and motion transfer baselines in dynamic fidelity and text alignment and progressively relaxes the composed latent toward the model's learned distribution before ODE sampling.
