摘　　要：提出了一种交互式变换树种和地面的方案,并结合微软公司新推出的Direct3D技术和VC++开发环境,实现了不同种树木在不同地表生长环境中的真实性模拟,建立了虚拟异龄树木生长环境模型和异龄多种模型,避免了传统的几何建模对时间和空间的耗费,帮助林业从业人员在普通的微机上对森林进行有效的监测和管理,从而提高林木生产量和资源利用率。The thesis combines corresponding picture process technology, researches the reconstruction of trees,three dimensional model from the two-dimensional picture, proposes one solution that can interactively transform the species of tree or the surface, finally adopts the three- dimensional animation technological Direct3D with VC development environment to realize the authentic simulation of the different species of trees in different surface habitat. Render a virtual environment where different age of trees grow and model all kinds of trees,that users can change the species of trees and surface, and offer forestry workers parameters of trees. This paper avoids exhaust on space and time that traditional geometry-based modeling method has arose.So make forestry workers carry on effective monitoring and management to the forestry and improve the amount of production of forest and resource utilization ratio.
