水稻生长可视化模拟系统的设计与实现

Design and realization of 3D visualization system for rice plant modeling

针对目前国内外虚拟作物的研究现状,在Windows平台上,使用OpenGL图形接口,采用面向对象编程技术,设计并实现了一个集水稻形态模拟及可视化、场景动态渲染、水稻生长动画等功能的三维结构可视化模拟系统原型.首先结合水稻的空间结构特点,基于参数化L系统,在器官尺度上模拟了单株水稻的拓扑结构.在此基础上,结合水稻的生长特性,构建了水稻生长的有限状态自动机模型,实现了对水稻动态生长过程的可视化描述.简述了系统的总体结构及基本功能,论述了系统设计与实现过程中涉及的关键技术,并给出了系统的界面以及实现的一些典型效果图.

Considering the research situation of virtual crops,a new 3D visualization simulation system for rice plant modeling is designed and realized with C＋＋ language in the environment of Visual Studio 2005 and OpenGL,and the technique of Object-Oriented Programming is used.Based on the growth laws and the topological structure’s characteristics of the rice plant,Parametric L-system is used to simulate its topological structures,and finite-state automaton is employed to describe the growth and development processes of rice plant.The system requirement is firstly analyzed,and then the general structure and basic functions in this system are introduced.The key techniques in the designing and implementation process in this system are discussed.Finally,the interface of this system and some typical effect pictures are given.
