摘  要：
通过对.X文件结构和内核的详细解读,给出了复杂模型的.X文件转换方法,并以构建一大型林分三维场景为例,阐述了对其高效、快速建模的方法过程。针对树木和林分形态结构的多样性、复杂性和信息量大等特征,利用所建树木基础模型,快速群生林分中树木模型及其.X文件,根据样地属性和对应.X文件建立林分三维模型。实验结果表明,利用.X文件表述复杂模型,不仅可以大大提高模拟大型复杂三维场景的速度,而且能够减少对原始数据的依赖,降低算法复杂度,提高建模效率。

摘  要：
Through minutely unscrambling the structure and kernel of.X file, the conversion method of.X file for complicated model was given. By taking the construction of a large forest 3D scene as the example, the methods and processes for high-efficient and rapid modeling were expounded. Taking into account the characteristics of tree and stand structure's diversity, complexity and large amount of information, and using the basic tree model constructed, the tree models and theirs.X files which grew quickly by clusters, and according to the sample plot properties and the corresponding.X files, the forest stand 3D model has been set up. The results show that the expression of complicated model by using.X file not only could raise the speed of simulating large complicated 3D scene but also could reduce the dependence on the original data, low down the complexity of the algorithm, and improve the efficiency of modeling.
