Abstract: 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.
