PhysMAS: Physics-Grounded Multi-Agent Synthesis of Compositional 4D Gaussians

Efficient, fully automatic, and physically plausible 4D Gaussian synthesis is an important goal for dynamic scene generation. Recent physics-based methods couple 3D Gaussians with the Material Point Method (MPM) to generate physically driven motion, but extending this paradigm to heterogeneous multi-part objects and in...

Physically Plausible Video Generation via Visual-Semantic Chain-of-Events Conditioning

This paper reformulate PPVG as event-centric generation by representing physical evolution as a chain of causally connected and physically constrained events, and generates videos with superior physical plausibility across diverse domains.

Evidence-Driven Dynamic Visual Selector for Efficient Long Video Understanding

A fine-grained dynamic visual selection framework named EviSelect, grounded in the target MLLM internal attention evidence, which efficiently approximate attention maps of the target MLLM using highly compressed visual inputs and sparse attention, well-aligned to the full counterpart.
