ABSTRACT:
In one aspect, an image of an event is obtained from a camera, and an object is detected in the image. Data of a textured 3d model of the event and data from the object are combined to depict virtual viewpoints of the event which differ from a real viewpoint of the camera. The object is at least partially faded out at a virtual viewpoint which meets a specified criterion, such as a specified angular offset, or exceeding a specified difference from the viewpoint of the camera. The fading can occur over multiple virtual viewpoints, or over a time period in which the fading is otherwise apparent to a human viewer. In another aspect, an animation is provided in which one object is faded out at a specified virtual viewpoint so that it does not fully occlude another object. For instance, the objects can be participants in a sports event.
