The paper introduces KnockGS, a framework that calibrates the elasticity and density of 3D Gaussian objects by analyzing their dynamic response to known forces. By extracting temporal response features from observed dynamics, KnockGS estimates material scales, freezes them into the simulator, and demonstrates that these estimates remain accurate for unseen interactions. Evaluation shows that KnockGS outperforms alternative methods in parameter recovery and response fidelity across diverse material targets.

3D Gaussian Splatting (3DGS) can reconstruct a captured scene photorealistically, but the resulting representation does not by itself support physical interaction. Robot simulation instead requires ob...
The paper introduces a Gaussian‑process state‑space model (GP‑SSM) for constitutive modeling of quasi‑brittle materials, replacing traditional internal variables with latent states learned from stress‑strain data. The GP‑SSM provides uncertainty quantification, enforces physical constraints, and maps latent states and strain tensors to stress responses via a sparse multi‑output GP. The trained model is implemented in Abaqus/Explicit and validated through four cases, demonstrating accurate reproduction of RVE‑scale histories, confinement effects, unloading behavior, and structural responses comparable to the KCC model.
