US Patent 7612777 Animation generating apparatus, animation generating method, and animation generating program

An animation generating apparatus for generating a three-dimensional animation tracking a moving object includes a camera parameter setting section setting a point of regard and a point of view based on a current position of the moving object using route data indicating a route of the moving object so that the point of regard is located on the route and the point of view is located behind the point of regard along the route, and a rendering processor generating an image by retrieving necessary rendering data from three-dimensional map data based on the point of regard and point of view set by the camera parameter setting section.
