In order to model complex hair styles, such as curly hairs and wavy hairs, we first construct five types of surfaces and three curves: curved cylinder, curved circular frustum, curved prism, curved edged frustum, curved revolving paraboloid, and curved cylinder helix, curved circular frustum helix and curved revolving paraboloid helix. Then we give the expressions for points and normal vectors on these surfaces, suitable to composition.
