IFS系统在植物形态模拟中的应用

Plant Simulation Based on Iterated Fractal Systems

IFS系统是模拟植物形态的一门重要技术。首先分析迭代函数系统中IFS码产生原理,阐述IFS如何模拟植物形态,然后依据拼贴定理,研究IFS码的变换特点,并利用IFS码的连续性探讨IFS码变换的规律及表现效果。另外通过增加IFS码,对分形图进行变换,逼真模拟森林、草地等自然景观。

The present work concerns the development of iterated function systems as a practical tool for the production of two dimensional images and animation of plant. The solution of plant simulation is achieved using a random iteration algorithm with IFS codes varied continuously. The IFS codes are found interactively by Collage algorithm based on Collage theorem. The characteristics and transformation of the IFS codes in plant simulation application are discussed with some simulation example. The natural scenery,such as forest and brushwood,are represented by adding IFS codes.
