Abstract
3d textured objects are provided for virtual viewpoint animations. In one aspect, an image of an event is obtained from a camera and an object in the image is automatically detected. For example, the event may be a sports event and the object may be a stationary object which is detected based on a known location, color and shape. A 3d model of the object is combined with a textured 3d model of the event to depict a virtual viewpoint which differs from a viewpoint of the camera. The textured 3d model of the event has texture applied from an image of the event, while the 3d model of the object does not have such texture applied, in one approach. In another aspect, an object in the image such as a participant in a sporting event is represented in the virtual viewpoint by a textured 3d kinematics model.
