    Visualization of individual Mongolian Scots pines in the plantation conditions based on characteristic parameters of morphological structures

    • 摘要: 为更加直观地展示樟子松人工林单木的整个生长过程,将系统分析方法和数学建模技术应用于樟子松人工林单木的形态模拟。通过对樟子松人工林单木形态数据的定量分析,结合前人的研究成果,构建了樟子松人工林单木形态模拟模型,并以VC++6.0为开发平台,利用OpenGL构建了樟子松人工林单木生长模拟系统,整个系统由形态模型模块、树冠结构模块、生长模型模块、可视化模块、场景控制模块、数据库和人机交互界面组成。系统运行结果表明:该系统实现了樟子松人工林单木生长机制与形态特征可视化表达的有机融合,展示了树冠结构模型、生长模型与可视化有机融合的思路;该系统不仅能很好地模拟樟子松人工林单木的形态特征,还能较逼真地实现樟子松人工林单木生长过程的模拟。樟子松人工林单木的可视化为人工林的可视化经营提供了基础,同时对于其他树种的可视化表达也有很好的借鉴意义。

       

      Abstract: In order to display more directly the dynamic growth process of individual Mongolian Scots pines in the plantation conditions, we employed a systematic analysis method and a mathematically modeling technique to simulate the morphological characteristics of individual Mongolian Scots pines. By referencing previous research of crown structure models, we established the morphological simulation model of individual Mongolian Scots pines through quantitative analyses of its morphological field data. Then, the growth visualization system was established with the OpenGL on the developing platform of VC++6.0. The system is composed of a morphology model suite, a crown model suite, a growth model suite, a visualization suite, a scene control suite, a database and a users interface. The operation shows that the system realizes the organic integration between the growth mechanism and visual expression of morphological characteristics of individual Mongolian Scots pines, and also well displays the concept of organic integration among crown structure model, growth model and visualization model. Meanwhile, the system can vividly simulate the morphological characteristics and growth process of individual Mongolian Scots pines. Obviously, our work lays a foundation for plantation visualization management, and also offers a good reference for the visualization of other species.
