摘要/Abstract

摘要： 提出一种基于物理的花的开放与凋落的动态模拟算法与叶片随季节时变动态算法。以五种花为代表,依据所收集的主要器官形态学数据建立各种花卉的模型。花朵动态仿真分为两个阶段：开放过程与凋落过程。通过控制Bezier曲面上控制点的变化,来模拟花朵开放过程;通过基于物理的方法,模拟花瓣凋落过程。通过纹理合成算法模拟叶片的颜色随季节变换的动态效果。实验结果表明,该算法能够有效地模拟不同品种的花的开花过程和在风的影响下花瓣的凋落过程,具有一定的应用价值和广阔的发展前景。

Abstract: This paper presents physically-based simulations of dynamic algorithms of the blossom and fading of flowers as well as the time-varying leaves following the seasons. The models of the flowers are constructed according to the previously collected primary biological data of organs of flowers. The dynamic simulation is presented by two phases: the process of blooming and the process of fading. To simulate the former, the curved surfaces of petals are controlled by controlling the points on the Bezier surface; for realizing the simulation of the latter, the physical method is used. The dynamic effects of colors of leaves according to the changes of seasons are simulated by the texture synthesis algorithm. The experimental results show that the proposed algorithm is able to effectively simulate the process of blossom and fading of different kinds of flowers under the influence of the wind, which proves its application value and broad prospects for development.

Key words: flower modeling, blooming dynamics, litterfall dynamics, time varying, physical simulation
