Abstract

In order to express undulation of a surface of an object realistically, a dynamic picture image generation device comprises a movement amount computation unit, which computes the movement amount for a vertex based on the connectedness, which is the degree of connection of a vertex to each skeleton, and on the reference movement amount, set for each skeleton of a model, which is the maximum value of the movement amount of a vertex connected only to the skeleton; a direction computation unit, which computes the movement direction of vertices comprised by each polygon; and a coordinate computation unit, which computes the coordinates of a vertex after a prescribed time, using the movement amount computed by the movement amount computation unitand the movement direction computed by the direction computation unit
