Our method requires animators to use their intuition to decide the camera positions for the rough hair sketches. Three-dimensional position points from the hair database sequence are then projected onto the image plane of he rough sketch. The data thereby become two-dimensional. Then we carry out matching in the 2D image plane with an x- and y-axes, comparing the angle between hair segments (Fig. 6). More specifically, we measure the difference in the angles between the data made from the rough hair sketches and the data of the hair sequences from the motion database projected onto the image plane. Then we compare this data using Eq. 1 from the hair root to the edge. We select the hair motion sequence that has the smallest error at the key frames
