通过对植物根系的形态结构分析,提出了根单元的定义及其相关的建模参数,并进一步实现了基于根单元的根系拓扑结构。利用Unity3D父子对象逻辑及相关的消息传递机制,实现基于参数标定的根系三维建模架构。使用相对控制点路径、截面图形边界计算、空间平面坐标变换技术、Mesh三维网格算法实现了根系三维模型。层级树形结构与相对尺寸、相对时间的整合,实现了植物根系的生长仿真。结合Shader着色技术,完成了通过图像完成根材质建模,达到了真实仿真的效果。实现的根系模型具有智能设计、动态生长的特点,且不同的特征参数输入,可以实现不同种类的植物根系仿真,具有良好的通用性和适用性。

By analyzing the morphological structure of plant roots,the definition of root unit and its related modeling parameters were proposed,and the root topological structure based on root unit was further realized.Using Unity3D parent-child object logic and related message passing mechanism,the root three-dimensional modeling architecture based on parameter calibration is realized.The root system 3D model is realized by using relative control point path,section graph boundary calculation,space plane coordinate transformation technology and Mesh 3D Mesh algorithm.The integration of hierarchical tree structure with relative size and relative time realized the growth simulation of plant roots.Combined with the Shader technology,the root material modeling is completed through the image,and the real simulation effect is achieved.The realized root model has the characteristics of intelligent design and dynamic growth,and different characteristic parameters can be input to achieve different kinds of plant root simulation,which has good versatility and applicability.
