Xiaomi's self-developed visual generation framework, WorldCast, has been integrated into the REDMI K100, enabling the transformation of static photos into 3D videos with camera movement effects such as orbiting and dolly zoom, while maintaining character feature consistency throughout the generation process. Together with multiple other features, it forms the phone's AI imaging feature matrix. The framework overcomes two major challenges: precise tracking of complex camera movement trajectories and maintaining character identity consistency under large-angle viewpoint changes. It constructs 3D point clouds through dimension elevation using a depth estimation model, introduces a geometrically aligned memory attention mechanism to supplement information in invisible regions, and builds dedicated training datasets and evaluation benchmarks. In relevant benchmark tests, all its camera control and character consistency metrics rank first, with multiple core indicators standing out and image quality in the top tier.
