基于WebGL的参数化三维树木建模

Parametric modeling of 3D tree based on WebGL

以网络作为平台,综合考虑树木的拓扑结构和分枝结构,建立层级型树木形态结构参数,实现了基于WebGL的交互式参数化三维树木模型在线实时构建,解决了现有在线树木建模软件难以控制树木整体形态的问题,在三维场景中通过旋转、缩放、移动等交互操作多视角地展示树木模型。实验表明,基于WebGL的交互式参数建模方法直观灵活、交互性强、操作便捷、用户体验流畅。

In this research,a WebGL-based prototype for parametric modeling of tree was introduced,and topology and branch structure of tree was considered to establish a hierarchy parameter set,providing the flexible and intuitive operation to explore the 3 D scene,which can model tree based on morphological characteristics. This method solved the problem that the existing online tree modeling applications are difficult to control tree silhouette. The experiments proved our prototype is intuitive,flexible and interactive,meanwhile,through the convenient operation it provides fluent user experience.
