WorldString

Builds neural digital twins of real-world objects from sparse keypoints, learning token-based representations of 3D point clouds to reconstruct geometry and deformation over time from RGB-D capture. Demonstrated on articulated objects (robot hands), skinned characters, soft/deformable items and quadrupedal robots — actionable representations for robotic interaction.
