Abstract
A dragonfly is a familiar insect by which the sense of season can be shown. The expression of a dragonfly by CG can be expected as an element improving the sense of season in landscape simulation, virtual reality, etc. This paper proposes the flight model of a dragonfly based on aerodynamics. In this model, a dragonfly can be made to fly in real time considering the force caused by the flapping of the wings, performing flight characteristics including steep rise, sudden stop, hover and rapid turn. Furthermore, the flight route of a dragonfly can be easily established depending on the control-points placed in the space.
