Abstract
The goal of this thesis is the synthesis of full-body motions to achieve desired martial arts attack actions and keep the human body balanced. We control an approximated model of the human skeleton in the physical simulation environment and use optimization algorithm to find an approximate optimal solution of desired motion. Given objective functions and the initial state of the skeleton, our method can find a motion sequence that minimizes the energy function values (local minimal). We use positions of limbs and the speed of hands in optimizing objective functions. We give a position of the target we want a character to attack. If its right hand does not pass the position at a specified time, the penalty increases. The objective function of balance will increase the penalty value when the center of mass of full-body is away from the target at desired position. Finally, we achieve the goal that a human-character can punch a target at specified position, while keeping its full-body balance.
