Realistic virtual characters generated by computer graphics are increasingly required in broadcasting programs. We propose an algorithm that implements interactive, real-time motion generation for the creation of virtual acrobats that perform complex circus acrobatics using a motion generation engine to support production. To facilitate control, we designed a graphical user interface and a minimum set of inputs which give a very effective result in motion. For fast computation, we designed each character and other objects with minimum dynamics construction to perform each motion. Because a circus acrobat usually requires large space, the motion capture system cannot be used. Furthermore, traditional key-frame animation cannot apply the external forces that are important to the motion. To solve these problems, our algorithm uses dynamics simulation and is able to create a variety of motion.
