自然场景中三维植物的建模

三维植物建模是虚拟自然场景生成过程中的关键问题之一,而植物建模主要考虑分枝结构和叶子这两个重要因素.通过将曲线细分思想引入到上下文相关的L系统推导规则中,并改变传统的线性数组字符存储结构,提高了L系统分枝建模过程的真实感和计算效率;同时在植物叶子造型中采用轴变形方法和纹理映射技术,提高了植物叶子造型的真实感.在此基础上给出了改进的植物生长状态演化算法,并给出了实验算例.

Simulation of Three-Dimension Plants in Natural Scenes

Braches and leaves are two important elements of plant,so must be mainly considered in simulation.This paper expanse traditional L-system through applying the notion of curve fraternizations into derived rules of context-sensitive L-system.Associated with the syntax of L-system,new solution to form branches based on binary tree were explored,replaced traditional store method of linear array.Additionally,this paper uses axial deformation method and texture mapping technology to model plant leaves.Finally,giv...
