摘　　要：以杉木为例,采用从可视化模拟角度设计的调查参数调查杉木形态结构,根据实际调查数据对杉木形态结构特征进行了分析。结合生长曲线控制下的迭代函数系统方法,采用面向对象的设计方法,根据DIRECTX9.0提供的API及模型渲染技术,在.NET和DIRECTX9.0平台上,使用C#语言建立了杉木单木生长可视化模拟系统,实现了单株杉木静态和动态的三维可视化模拟。Along with the development of computer techniques,the application of computer in three-dimensional visualization simulation of plant growth process has been paid more and more attention.Taking Cunninghamia lanceolata as an example,the morphological parameters from the perspective of the visual simulation were designed and the trees＇ morphological characteristics were analyzed based on the survey data.Combined with IFS（Iterated Function System） under the control of the growth curve,by using Object-oriented design methods,and according to API and model rendering technology provided by DIRECTX9.0,a three-dimensional visualization system on the growth and development of C.lanceolata individual tree were developed on the.NET and DIRECTX9.0 platforms,which realized the static and dynamic three-dimensional visualization simulation.
