Abstract:
An image generation apparatus for generating an image at a given viewpoint within an object space, said image generation apparatus comprising:means for causing a moving body to move over a course within said object space, based on manipulation data that is input from a manipulation means and flow data for a fluid that is set along said course; and means for generating an image as seen from a given viewpoint of the moving body within said object space, which is an image comprising an image of said course, the given viewpoint of the moving body within said object space changing based on the movement of the moving body that moves based on the manipulation data that is input from said manipulation means and the flow data for the fluid that is set along said course, wherein a flow-velocity vector at the position of said moving body is obtained by interpolation based on flow data that is set for a first array of sample points on said course and position data for said moving body, said moving body being moved in accordance with the flow-velocity vector.
