Xiaomi Integrates WorldCast 3D Camera-Tracking Framework into REDMI K100
Xiaomi has integrated its WorldCast 3D visual generation framework into the REDMI K100 smartphone. The feature allows users to select a static 2D photo from their album and have AI generate a dynamic 3D camera-tracking video while keeping the character's facial features and clothing consistent. This development bridges academic computer vision research and consumer applications, successfully commercializing cutting-edge AI generation technology on mobile hardware. It enhances mobile imaging capabilities and paves the way for more advanced 4D video generation technologies. The WorldCast framework interprets the depth structure of a 2D image to reconstruct a 3D scene and simulate realistic camera trajectories like orbiting, zooming, and tilting. Xiaomi plans to use this foundational tech to explore longer continuous video generation and more complex camera movements.
## BACKGROUND
WorldCast is a recently published AI framework designed for world-consistent character video generation with large-angle camera control. It operates by combining trajectory-aligned geometry guidance with geometry-aligned multi-view character memory to maintain appearance consistency during camera motion.
