 ## Model Description
 MemCam is a memory-augmented framework for scene-consistent interactive video generation, built on [Wan2.1-T2V-1.3B](https://huggingface.co/Wan-AI/Wan2.1-T2V-1.3B). It treats previously generated frames as external memory and dynamically retrieves the most viewpoint-relevant frames via co-visibility estimation, enabling faithful scene reconstruction even after 360° camera rotations.
