This paper presents an efficient method for generating complex motion of a human-like figure such as circus acrobatics including calculations for gravity and elasticity. The authors apply several motion dynamics techniques generated by using a motion generation engine. This allows iterative trial-and-error interaction to perform a wide range of acrobatic motion with a well designed user interface entailing the mouse, keyboard and joystick. Using this generator, some of the physical control parameters for the character such as gravity, rope angle, trampoline strength etc can be changed to affect the characters motion. We improved the dynamic motion algorithms for fester computation and we simplified the linked object structure and collision detection routines for a smoother operation during real-time interaction. As a results we can easily control the character's behavior on a variety of apparatus such as the trampoline, bungee swing, flying trapeze etc. This paper presents the methods we used to improve the motion generator using an interactive real time simulation. The methods used can be applied in the creation of games, movies and a broad repertoire of entertainment.
