Amortized Inverse Kinematics via Graph Attention for Real-Time Human Avatar Animation

ArXi:2604.16629v1 Announce Type: new Inverse kinematics (IK) is a core operation in animation, robotics, and biomechanics: given Cartesian constraints, recover joint rotations under a known kinematic tree. In many real-time human avatar pipelines, the available signal per frame is a sparse set of tracked 3D joint positions, whereas animation systems require joint orientations to drive skinning.
