基于L-System模型的Web三维果园构建方法研究

网络技术和虚拟现实技术的发展为农作物生境的展示提供了多样化的方式。笔者研究在 L-System植物模型的基础上，提出一种简单、快速的在线三维果园构建技术方案：采用Xfrog软件构建果树三维模型，运用Unity3D引擎设计果园三维场景并实现人工交互，以热带水果——莲雾作为应用范例，构建Web三维莲雾园模型，模型具有真实感强、交互功能丰富、操作简单等特点。该方案为果树生长研究、农业景观规划和乡村旅游推广等应用提供三维可视化的展示方式。

Study on Construction of Three-Dimensional Orchard Based on L-System Model

The development of network technology and virtual reality technology provides a variety of approaches for demonstration of crop habitats. Based on the L-System plant model, the author proposed a new method to build a simple and fast web three-dimensional orchard model: to construct a three-dimensional model of fruit tree by Xfrog software and apply Unity3D engine to designing three-dimensional orchard and achieving scene interaction. As an application example with wax, the author built web three-dimensional model of wax plantation, which was highly characterized with reality, rich interactive functions and easy operation. And therefore, it was greatly bestowed with the capacity to provide the three-dimensional visualization for some agriculture applications, such as the growth of fruit tree research, agricultural landscape and rural tourism promotion.
