Abstract
Displaying extreme expressions such as scared until sweating is not easy task that can be accomplished in 3D games and facial animation simulation in real-time. Several difficulties faced by researches such as the complexity of simulation including physical properties of the muscles, emotions, properties of fluids and texture element. The next part is how to control the facial animation with one of the two sweating generators simultaneously. This research present techniques for generating extreme expression in 3D facial animation. The Facial Action Coding System (FACS) is employed to describe and generate facial expressions. It breaks down facial actions into minor units known as Action Units (AUs). Facial expressions are generated by combining specific independent Action Units. The generated expressions cover sadness, anger, happy and fear. The first type of sweat is dropping sweat using particle system. The other type of sweat is texture based, when the sweat is stimulated the texture drop will flowing down around surface of the forehead area. The technique presented in this paper is believed able to give more realism to virtual human by providing features of extreme expression.
