摘　　要：树在虚拟场景中的构成中占有很重要的地位.论文跟据不同虚拟场景中绘制三维树木的特点,介绍了贴图法画树;提出了用分形方法对三维树木进行真实绘制;并讨论了加速虚拟场景中三维树木绘制的技术.实践证明:在VC和OpenGL的环境下,用本文方法在可漫游虚拟场景中产生树模型,在实时性与真实感方面均取得了不错的效果.Trees play an important role in the virtual scenery landscape. The texture mapping of tree-image is introduced and the method of drawing 3D tree based on fractal is presented. The technique of speeding up drawing 3D tree in virtual scene is also discussed according to the demand of drawing 3D tree in different virtual scene. Experimental results show that with the tools OpenGL and VC, the modeling of tree in roaming virtual scene demonstrates satisfactory effects in real-time and third dimension.
