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.
