Show model combines growth model, math model and VR technologies to design the proper object structure of each organ of virtual plant. First of all,research background, research content of virtual plant area and Virtual Reality technology are introduced. The concept of VR and research content of virtual plant are defined. Secondly, we analyze math model of virtual plant, including Bezier curve, NURBS curved surface, fractal system, L-system and Catenary curve. Thirdly, we give show model of virtual plant in detail. Finally, the design of the platform and growth model on XML script is introduced , and how to show the virtual plant in the platfrom is discussed too.

本文首先介绍了虚拟植物领域的研究背景、研究内容和虚拟现实技术，明确了虚拟现实的概念和虚拟植物的研究范畴，然后介绍了虚拟植物器官的数学模型，对各个器官展开了拓扑结构分析，建立有针对性的数学模型，先后介绍了Bezier曲线，NURBS曲面，分形系统，L-系统和悬链线曲线，接着详细分类介绍了虚拟植物器官的显示模型，最后介绍了虚拟作物平台的设计，平台中基于XML脚本的生长模型，以及虚拟作物在作物平台中的显示。

And try to define it in the following aspects: I By using the characteristics of computer hyper text, carry out the combination of information techniques and math courses; II Use the modern information techniques as a basic tool for students in vocational schools to gain knowledge; III The combination of modern information technique and content of math course should face the students' cognizable structure. IV To develop interest is the ultimate purpose of this combination; There are explanations of typical cases and discs of courseware in this thesis. From the cases, we can found that the combination is feasible in some content. In order to put the theory into practice, this academic thesis also presents some questions worthy of further thought.
