基于L系统改进的虚拟植物原型系统设计

设计实现了基于L系统改进的虚拟植物可视化原型系统。该原型系统实现了微机平台上可视模拟植物生长，并取得了较好的试验效果。系统设计思想以植物可视外观展现为主要目的，结合了L系统和基于图像建模的优点，对植物器官的建模方法是基于能够反映植物器官主要特征的表面建模。其实现思路是在L系统所描述的植物拓扑结构的基础上,对预先定义好的植物器官网格面进行装配。与L系统相比较，有更好的外观效果和较低的时间复杂度。

Development Prototype of Virtual Plant Based on Improved L System

A prototype of virtual plant based on improved L system is designed. The platform can run well on personal computer, and achieved good visual result of simulating the growth of virtual plant. The method combines the characteristic of L system and the visual result of image modeling. To construct main stem and major branch based on L system, growing the remainder of the plant based on plant organs model of mesh. The proposed method reduced the complexity of L system, and resulted in realistic view of virtual plant.
