Abstract: This paper introduces the two-half modeling technique, and proposes the modeling method based on the area filling modement, the texture shaggy mapping and the line form model.The embossment modeling method for China landscape paining is also demonstrated.The generating technique of the natural surface model is the key technique in the two-half modeling, we realized the reconstruction from the image to the model by using the recover technique, in which the album information is used to calculate the shell of the surface.
