Sketch-based Modeling and Animation of Floral Blossom

Summary form only given. Traditionally, synthesizing the animation of floral blossom is accomplished mostly manually and hence a time-consuming and laborious task. In this paper we propose an interactive biology-based flower modeling and animating approach. We model the initial shape of the floral components including petal, pistil, stamen and pedicel, and two terminal status of floral blossom with a parameterized sketching interface. The subtle geometry of the whole flower is created according to the phyllotactic rules. We then extract a set of growth parameters for describing the floral blossom, and build a dynamic growth model to regulate the continuous morphing of floral components in the process of blossom. Finally, a sequence of naturally deforming flower models is generated with these parameters. Our initial experimental results demonstrate that our approach can efficiently generate visually pleasing simulation of floral blossom, which is consistent with biological rules.
