A hybrid approach to animating the murals with Dunhuang style

In order to animate the valuable murals of Dunhuang Mogao Grottoes, we propose a hybrid approach to creating the animation with the artistic style in the murals. Its key point is the fusion of 2D and 3D animation assets, for which a hybrid model is constructed from a 2.5D model, a 3D model, and registration information. The 2.5D model, created from 2D multi-view drawings, is composed of 2.5D strokes. For each 2.5D stroke, we let the user draw corresponding strokes on the surface of the 3D model in multiple views. Then the method automatically generates registration information, which enables 3D animation assets to animate the 2.5D model. At last, the animated line drawings are produced from 2.5D and 3D models respectively and blended under the control of per-stroke weights. The user can manually modify the weights to get the desired animation style.
