Animation generating apparatus, animation generating method, and animation generating program

An animation generating method for generating a three-dimensional animation tracking a moving object, comprising:

• 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 a position of the moving object located on the route, and the point of view is located on the route of the moving object in a first direction and at a fixed distance behind the point of regard;
• generating an image directed from the point of view to the point of regard when the moving object changes direction by retrieving necessary rendering data from three-dimensional map data based on the set point of regard and the set point of view;
• and
• keeping the point of view directed to the point of regard and positioned on the route of the moving object traveling in a first direction at the fixed distance behind the point of regard when the direction of the moving object changes in a second direction perpendicular to the first direction.

A computer readable medium storing an animation generating program causing a computer to execute a process for generating a three-dimensional animation tracking a moving object, the program causing the computer to function as:

• camera parameter setting means for 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 a position of the moving object located on the route, and the point of view is located on the route of the moving object in a first direction and at a fixed distance behind the point of regard;
• and
• rendering control means for issuing a rendering command to generate an image directed from the point of view to the point of regard when the moving object changes direction by retrieving necessary rendering data from three-dimensional map data based on the point of regard and the point of view determined by the camera parameter setting means,
• wherein, when the direction of the moving object changes in a second direction perpendicular to the first direction, the point of view remains located along on the route of the moving object traveling in a first direction at the fixed distance behind the point of regard and directed to the point of regard.

An animation generating apparatus for generating a three-dimensional animation tracking a moving object, the apparatus comprising:

• a camera parameter setting section configured to set 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 a position of the moving object located on the route, and the point of view is located on the route of the moving object in a first direction and at a fixed distance behind the point of regard;
• and
• a rendering processor configured to generate an image directed from the point of view to the point of regard when the moving object changes direction by retrieving necessary rendering data from three-dimensional map data based on the point of regard and the point of view set by the camera parameter setting section,
• wherein, when the direction of the moving object changes in a second direction perpendicular to the first direction, the point of view remains located on the route of the moving object traveling in a first direction at the fixed distance behind the point of regard and directed to the point of regard.
