The 3D model animation plays an important role in the digital design and application. Though many scholars have got research achievements of 3D model animation, how to reproduce the national dance by 3D digital technology is a challenging problem now. This paper uses the motion capture technology to display 3D digital national dance and compared it with the method only based on the 3D model. Firstly, the motion capture equipment gets human motion data file and then creates 3D model which included skeleton, skin and weight work in Maya. By MotionBuilder, 3D model was combined with motion capture data. In this paper the real dance of 13 different nationalities finally is shown by virtual characters at virtual scene.
