【摘要】 林分场景的可视化构建,是基于林分的自身生长规律模型,通过计算机图形学的理论和虚拟现实的方法来实现的.以北京市昌平区油松人工林为研究对象,利用现有的森林资源调查数据,结合预测林分生长精度较高的胸高断面积模型,通过林分场景渲染的各种方法,实现了林分生长的可视化模拟.更多还原

【Abstract】 Stand visualization is realized based on a stand growth model and performed by using computer graphics theory and virtual reality approach.In a study reported in this paper,stand growth simulation of a Chinese pine plantation in Changping District of Beijing was fulfilled,using the existing forest inventory data and combining it with a stand basal area growth model which has high prediction accuracy,according to a variety of scene rendering methods.更多还原
