SimuScene: Simulation-Ready Compositional 3D Scene Reconstruction from a Single Image
Reconstructs interactive, simulation-ready 3D scenes from a single image by putting a physics engine in the loop of shape and layout estimation.
About
I'm an undergraduate researcher at Seoul National University, advised by Prof. Hanbyul Joo. I work on robot learning where 3D perception meets manipulation: teaching robots to understand the scenes they act in. Previously, I worked with Prof. Songhwai Oh at the Robot Learning Lab.
My long-term goal is to build robots that act in the open world as fluidly as people do: seeing a scene in 3D, reasoning about what to do, and carrying out long-horizon, dexterous behavior reliably. Toward this, I work on turning what a robot sees into simulation-ready worlds, grounding language in 3D for manipulation, and generative planners fast enough to run inside the control loop.
