We digitally restored the original Great Buddha and the main hall of Todaiji temple. Todaiji temple has been destroyed by natural and artificial disasters and rebuilt for a number of times. As a result, the shapes of the current Great Buddha and its main hall are slightly different from the original states. We reconstructed the 3D models of the original Great Buddha and its main hall. The 3D model of the original Great Buddha was reconstructed by morphing the 3D model of the current Great Buddha, which was obtained by laser scanning and Modeling-from-Reality techniques. The 3D model of the original main hall was reconstructed by assembling the partial 3D models of the main hall of Toshodaiji temple. We combined these models and visualized the original state of Todaiji temple by Computer Graphics techniques.
