InterSing: Explicit Interaction Dynamics for 3D Duet Singing Animation and Beyond

On September 7, 2026, the arXiv cs.CV preprint platform released a new model called InterSing. This research proposed a framework based on explicit interaction dynamics to solve the challenge of generating three-dimensional duet singing animations. InterSing achieves more natural motion synchronization and emotional expression by modeling the dynamic interactions between singers. This work is not limited to duet scenarios but also extends to more complex multi-person interaction animation generation tasks, providing new technical approaches for virtual idols, music video production, and human-computer interaction.
