Abstract:
An animated image generating apparatus in which each leg model is formed by two skeletons, one extending from a waist to a knee and the other extending from the knee to a foot, and the positions of the respective leg models are determined by position calculation of the skeletons, comprising:model setting means for specifying a dynamic model formed by a mass particle given at a waist position and a coupling body coupling a substantially middle point between the feet of both legs and the waist, foot determining means for determining the positions and speeds of the feet of both legs, waist position calculating means for calculating the position of the waist by dynamic calculation based on the positions and speeds of the feet of both legs given by the foot determining means using the dynamic model, and knee position calculating means for calculating the positions of the knees of both legs based on the positions of the feet of both legs determined by the foot determining means and the position of the waist calculated by the waist position calculating means.
