摘要
虚拟垂柳的造型和生长技术有着广泛的应用。通过分析垂柳的拓扑结构,提出了基于抛物线的方法来模拟柳条的形态,使用加扰动的方法生成了多种形态的柳叶,并给出了基于几何约束的dL-系统模型的生成规则实现垂柳的虚拟生长。实验结果显示生成的垂柳造型逼真,其虚拟生长过程自然,且具有较高的执行效率。
The technology that modeling and developing of virtual weeping willow is widely used. The topological architecture of weeping willow, and the generation rules, are analyzed. Branch shape is simulated by parabolic method, and leaves are generated by the perturbation method. A dL-system with geometry restriction is provided to implement the continuous virtual developing of weeping willow. The experiment shows that the model of the plant is realistic and its development is natural.
