摘　　要：高真实感的动态仿真技术一直是古典园林虚拟研究的重点和热点,针对如何实现园林景观的数字化平台设计,本文提出了一种依托高真实感虚幻引擎开发工具包(Unreal Development Kit,UDK)与强大植物建模软件SpeedTree相结合的完整制作方案,它使园林虚拟仿真交互更加真实.该方案从基础建模、贴图处理、植被添加、户外光影和动效制作等方面提升了古典园林的虚拟仿真表现;模型的流线性表面及后期不透明贴图处理解决了古典园林中复杂模型的渲染时间长和真实感差的问题;根据UDK引擎和SpeedTree插件完成了植被的真实还原及复杂的光影问题,解决了日夜交替、光影浮动的动态逼真效果;最后探讨了虚拟技术与古典园林设计相结合的技术优势和发展前景.Dynamic simulation technology of high sense of reality is always the hot spot in virtual research of classical gardens,according to the problem of how to realize the landscape designation of digital platform,this paper has proposed a novel scheme makes the garden virtual simulation interaction more real,which relied on the combination of the high realistic graphics image display engine UDK and the powerful plant modeling software ＂Speed Tree＂.The scheme improved the virtual simulation performance of classical garden from the aspects of basic modeling,mapping,vegetation added,outdoor light and dynamic effect of making etc.The model of streamline surface and late opacity map processing solved the problem of the rendering time and realistic for complex model for the classical gardens;With the UDK engine and the Speed Tree plugin solved the problem of complex shadow and the vegetation real reduction,which solved the alternation of day and night and the effect of light floating dynamic vivid.At last,this paper has discussed the advantages and development prospects for the combination of the virtual technology and classical garden designation technique.
