Abstract
This paper presents an efficient method for generating complex motion of a circus acrobatics including calculations for external forces as the gravity and elasticity. Iinteractive circus simulation contents are demonstrated. The authors employ 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. The dynamic motion algorithms have improved for faster 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 in our interactive content
