摘　　要：畅春园文化遗址数字化复原的难点是四季植物的精细仿真,针对这一特点,研究了基于SpeedTree的植物仿真方法,不仅可以构建精细、逼真的各种植物仿真模型,以及丁香堤、兰芝堤、桃花堤、花海、竹轩等,而且可以精确的构建各种植物的LOD模型,优化各种植物模型,提高植物仿真模型的实时渲染速度;研究了逼真植物动态风效模拟,以及植物四季变化的动态仿真。实验表明,上述植物仿真方法解决了文化遗址数字化复原领域中的难点问题之一,有效的实现了植物的逼真仿真、风效模拟、四季变化动态仿真等自然景观。The difficulty of digital restoration of Changchunyuan cultural heritage site is the fine simulation of four seasons plants.According to this feature,the plant simulation method based on SpeedTree is studied.It can not only build fine and lifelike simulation models of various plants,but also build LOD models of various plants and optimize various plant models.This paper studies the dynamic wind simulation of realistic plants and the dynamic simulation of the four seasons of plants.Experiments show that the plant simulation method solves one of the difficult problems in the field of digital restoration of cultural sites,and effectively realizes the realistic simulation of plants,wind effect simulation,dynamic simulation of four seasons change and other natural landscapes.
