Parametric Modeling And Animation Of Flower

Virtual modeling and simulation technology has been widely used in many fields such as computer animation, games and visual. The existing modeling software, such as Maya,3DMAX, has its own flaws in modeling and animation design, This paper presented a new method that is parametric modeling and animation with flowers component. This paper enables users to reuse the existed flower pieces to create a new one. Instead of using interactive free deformation technology, our new system uses the parameter editing. Users only need to change a few simple parameter to control the new flower's shape, and generate the needed animation. This paper launched following several aspects.1) Constructing flower library. This paper reuses flower materials to constructing flower lib. The existed flowers are spited to pieces according to their structural characteristics and extracted their shape attributes. The materials is sorted, according to the overall topology of flowers, and organized by hierarchical structure for user-friendly.2) Parametric modeling of flower components. A new flower is modeled by combined different parts into assembly, using flower's topological structure. Component modeling approach enables users directly from the material directly from the existing modeling material for flowers, Not only can generate different structure and morphology of virtual flowers, more prominent feature of all users without flowers refresh local site, saving the user edit time, improve design efficiency.3) Flowers animation. This paper constitutes different animation parameters on different parts of the flowers, according to real flowers bloom principle and flower morphology, and then sets up key-frame animation parameters values to obtain animation using key-frame animation technique. For more authenticity, the research based on the physical movement control model formed blown animation, Plant flexibility joint model, driven by external forces, so that flowers produce flickereffect.Research results have already been integrated as a plug-in of the software MAYA, have flowers on the material reuse and parameter setting, users can complete the flowers modeling and animation design quickly by parametricmodeling and animation, by reusing the existed flowers.
