In order to preserve the correctness of objects we need use a lot of information, but it will affect the efficiency of time. Not only that, in some cases, we can not guarantee that the results can be maintained in the volume of objects, so that the final results do not conform to the user’s expectation. Therefore, we present a method that using tetrahedrons to fill the hollow structure of the 3D model with the purpose of keeping the original form and structure of the models. First step, we use a simple model as based model, and then use the structure of based model to fill two hollow structure of 3D models. When two models have some structure, we use as-rigid-as possible deformation method to deform these models. By the way, model even in the more exaggerated the change, the minor will not lose its characteristic.
