Abstract
A real-time video exploration (RVE) system that allows users to pause, step into, and explore 2D or 3D modeled worlds of scenes in a video. The system may leverage network-based computation resources to render and stream new video content from the models to clients with low latency. A user may pause a video, step into a scene, and interactively change viewing positions and angles in the model to move through or explore the scene. The user may resume playback of the recorded video when done exploring the scene. Thus, rather than just viewing a pre-rendered scene in a movie from a pre-determined perspective, a user may step into and explore the scene from different angles, and may wander around the scene at will within the scope of the model to discover parts of the scene that are not visible in the original video.
