基于手绘图形的三维分形树木生成技术

The Generation Techniques of Three-Dimensional Fractal Tree Based on Hand-Painted Graphics

在三维分形树木IFS递归算法的基础上,提出了一种将用户手绘简单、非真实感的二维树木图形变成复杂的和具有真实感的三维树木模型的方法,克服了传统迭代函数系统三维分形树木造型交互不方便、不直观的缺陷,并对IFS递归算法做了改进.

Based on the recursive algorithm of three-dimensional fractal tree IFS,we present a new method for converting a user＇s hand-painted graphics of a simple,non-realistic two-dimensional tree into a complex and realistic three-dimensional tree model,which can overcome the flaws of inconvenience and indirect perception of the traditional fractal interactive model,and the recursive algorithm of IFS is also improved.
