BendTwin: Robust Dense-to-Sparse Physical Reconstruction with Bending-Aware Differentiable Spring-Mass Models
BendTwin is presented, a bending-aware differentiable spring--mass framework for video-based reconstruction and future prediction of deformable objects and provides an effective approach for constructing mechanically faithful digital twins from sparse-view RGB-D videos.
