Design and Implementation of Virtual Visualization Growth System of Individual Mongolian Pine in Plantations

Abstract:

The visualization of individual tree dynamic growth process provides a more intuitively visual display of individual tree growth process and effectively supports the forestry education and scientific researches. This paper presents an approach of combining the systematic analysis method and mathematical modeling techniques to realize the visual expression of the dynamic growth process of individual Mongolian pines in plantations. Quantitative analysis of morphological data and theoretical growth equation lay the foundation for establishing the dynamic growth model of individual Mongolian pines, which includes a primary branch diameter (BD) growth model, a primary branch length (BL) growth model, a height growth model, a diameter at breast height (DBH) growth model, a height of clear branches (HCB) growth model and a crown length (CL) growth model. Consolidating results of previous study--crown structure models and the development platform of VC++6.0 and OpenGL, we successfully established the virtual visualization system of individual tree growth for Mongolian pine plantation, and therefore implemented the nice integration of growth mechanism and morphological characteristics of individual Mongolian pines in plantation. The visual expression of individual tree growth provides a prerequisite for the visual forest management. In addition, it also offers a good reference for the visualization of other species.
