CharacterShot is a controllable and consistent 4D character animation framework that enables the creation of dynamic 3D characters (i.e., 4D character animation) from a single reference character image and a 2D pose sequence.
CharacterShot utilizes a powerful 2D character animation model based on a DiT image-to-video architecture. It lifts these animations to 3D using dual-attention modules and camera priors to ensure spatial-temporal and spatial-view consistency. The final representation is optimized using neighbor-constrained 4D Gaussian Splatting, resulting in stable and continuous character representations.
