AI-assisted 3D animation software for creating realistic character animation and physics simulation. Cascadeur uses machine learning and physics algorithms to help animators create believable motion with automatic secondary animation, physics-based corrections, and AI pose suggestions. Features include AutoPhysics for realistic motion, AutoPosing for natural poses, spine simulation, trajectory editing, and reference video analysis. Used by game developers, filmmakers, and animators to create high-quality character animations faster than traditional methods.
