Animation generating apparatus, animation generating method, and animation generating program
First Claim
1. An animation generating apparatus for generating a three-dimensional animation tracking a moving object, the apparatus comprising:
- 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 means for 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 point of regard and the point of view set 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 on the route of the moving object traveling in the first direction at the fixed distance behind the point of regard and directed to the point of regard.

Abstract
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.

8. 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. - View Dependent Claims (9, 10, 11, 12, 13)

14. 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. - View Dependent Claims (15, 16, 17, 18, 19)
