The PSIVG Advantage
Our Physical Simulator In-the-loop Video Generation (PSIVG) framework integrates physics simulation guidance into a pre-trained video diffusion model to generate videos whose object motions respect real-world physics while maintaining high visual fidelity. This novel approach addresses the critical gap where current diffusion models struggle with basic physical laws like gravity, inertia, and collision. By using a physical simulator to guide motion, PSIVG significantly enhances realism and reliability, making AI-generated videos more compelling for diverse applications.
Precision Perception for Simulation
The perception pipeline in PSIVG translates a generated template video into simulator-ready assets. This involves extracting three key components: foreground moving object dynamics, the physical environment they interact with, and camera motion. Key steps include 3D mesh reconstruction of foreground objects (using InstantMesh), 4D scene reconstruction for background geometry and camera poses (using ViPE), and precise estimation of initial object states including linear and rotational velocities via 2D feature matching (SuperGlue).
Integrating Physical Accuracy
PSIVG adopts an MPM-based physical simulator to generate physically accurate scene dynamics. Scene initialization is crucial, involving determining the simulation domain, placing and scaling objects, inferring physical properties (like density and Young's modulus using a GPT-5 guided hierarchical prompting framework), and setting initial states. After simulation, the system renders RGB frames, segmentation masks, and pixel correspondences using Mitsuba, which serve as explicit guidance signals for the video generator.
Enhancing Texture Consistency with TTCO
Test-Time Texture-Consistency Optimization (TTCO) is a lightweight, test-time procedure designed to improve texture consistency and prevent flickering in moving objects. It optimizes learnable parameters by applying a pixel-correspondence loss using data from the physical simulator. This localized optimization, focusing on text embeddings and feature-wise modulations for foreground objects, enhances texture stability without degrading the background, ensuring generated videos adhere to simulator trajectories and rotations more accurately.

Enhanced Realism in Complex Scenarios
PSIVG excels in generating videos for complex scenarios such as bowling collisions or objects being dropped, where traditional models often produce visually appealing but physically implausible motion (e.g., objects floating or fading). Our integrated physical simulator ensures that generated objects follow realistic trajectories, rotations, and interactions, directly addressing the limitations of diffusion models in capturing fundamental physics. This capability is crucial for applications requiring high fidelity to real-world dynamics, from film production to robotics.
