PhysGen3D: Crafting a Miniature Interactive World from a Single Image

Figure 1. PhysGen3D generates realistic, physically plausible motion from a single image and a text prompt by reasoning about geometry, semantics, and material properties. (a) An apple rolls under the influence of its initial velocity, friction, and shape, producing a natural progression over time. (b) Three animal figures interact dynamically, colliding after being propelled upwards and forwards. (c) A toy potato bounces back with soft-body dynamics in response to an initial downward force, capturing material-specific behaviors. PhysGen3D lets users quickly explore physics-driven object interactions and behaviors in a compact virtual scene generated from a single input image.
