摘　　要：植物的模拟一直以来都是计算机图形学的热点和难点问题,为了实现通过互联网在网页上方便、快捷地浏览具有逼真性、交互性的三维植物,论文从植物的生理结构出发,结合确定性L系统、参数L系统和原始的递归算法提出了一种植物建模的数学模型,并采用X3D结合JAVA作为实现语言,建立了树的轴结构、叶序和叶子的模型。用户只需实时地输入相应的参数,就可以快速、便捷地生成逼真的三维植物。Plant simulation is a popular and difficult issue in computer graphics these years.In order to conveniently and quickly browse the 3D plant which is realistic and interactive on web,a mathematic model of plant-modeling based on determination L-system,parameter L-system and the original recursive algorithm is proposed from the aspect of the plant physical structure in this paper.X3D and JAVA are chosen to generate a three-dimensional plant model quickly and easily after giving related parameters.The modeling of the branch structure of tree,the leaf arrangement and leaf is realized in this paper.
