植物真实感建模方法研究

1 引言许多植物的建模方法往往只注重模拟植物的生长,如L-系统主要是通过一系列产生规则模拟植物的生长过程,A-系统和忠实于植物真实结构和生长的系统同样也是着重于植物生长的模拟,由于没有植物的真实的三维表达模型,这些方法中植物的建模和真实感处理往往是脱节的,导致无法综合采用对植物的多种建模方法。而有些方法则注重于对植物的真实感表示,如对枫树的真实感处理方法,其应用的局限性也是显而易见的。

The Research on Plant's Realistic Modeling Method

Plant's 3D structure is quite complex. This paper presents an Open Synthetic Plant Modeling Method. It includes three partsplant's realistic representation model,synthetic modeling method and realistic display method. Branch is the base element of plant's realistic representation model and is simulated by cublic parameter surface. The synthetic modeling method is implemented by interactively using several simulation methods in the growth procedure of plant. Bark texture and leaf are added to realistically display the plant's 3D structure, Four test examples indicate that this method is feasible in plant's 3D modeling.
