森林景观的计算机建模与可视化研究进展

Advances in Forest Landscape's Computer Modeling and Visualization

从单棵树的建模、森林场景的绘制技术、森林生长模型分类与特点以及典型的虚拟森林景观系统等几个方面,对森林景观生态的计算机建模和图形可视化研究现状与发展趋势进行综述,就该领域的发展趋势和未来需要解决的关键问题进行总结。

Computer modeling and visualization of forest landscape recently becomes a hot topic, whose study can benefit such fields as ecology, forest management, physical geography and botany, etc. There are 3 major techniques to construct a visual model of vegetation： traditional polygon-based modeling, photo-realistic image-based modeling, and procedure-based modeling. Polygon-based model is widely used for plants and forest scenes rendering; image and procedure-based models provide more effective solutions for complex scenes simulation and deal well with massive data. The state-of-the-art development in this field is reviewed from the perspectives of single tree modeling, forest scenery rendering, forest growth model classification and characteristics, and typical virtual forest modeling systems. The trend and key issues to be solved in forest landscape ecosystem modeling and visualization are also discussed.
