This research introduces Phys4DGen, a framework that automatically perceives material properties for physics-compliant 4D generation, eliminating the need for manual specification by users.

• Creates realistic multi-material composite objects that behave naturally in simulations
• Leverages a novel material perception network to automatically infer physical properties
• Achieves state-of-the-art performance in generating physics-compliant 4D content
• Enables diverse physics-based animations without requiring user expertise in physics

For engineering applications, this breakthrough allows for rapid prototyping and testing of mechanical designs in virtual environments before physical production, significantly reducing development cycles.
