Spherical Rotation Decoupling
A technical method in panoramic video generation that models rotational transformations as rigid-body motions on the sphere (SO(3) group operations). This avoids geometric distortion introduced by processing rotations in planar coordinate systems, ensuring spatial consistency across panoramic frames.

SPW-Nav proposes three technical designs: spherical rotation decoupling, pose-aligned conditioning, and a multi-memory few-step generator.
Spherical rotation decoupling directly models the rotation transformation as a rigid body motion on the sphere (an operation on the SO(3) group) and then projects it back to the plane, rather than directly manipulating planar pixels.
