Based On IFS Theory Fractal Simulation Of Plant

The randomicity and scrambling of nature senery in formal is difficult to bedescribed by traditional means. Since 1970 when B.Mandelbrot lodged the fractal concept, as a burgeoning cross subject, it' s extensive attented by nonlinear academia. In the simulation of the nature scenery, the fractal technique shows its single advantage and become hotspot of pursuers today.Simulation of plant has been a hotspot in the field of computer graphics. With so many scenes included, nature often shows its self-similarity in common. An important mathematical implement, fractal geometry, characterizes this kind of feature perfectly. Fractal method has versatile representations. Choices between these forms should be according as practical need.Fractal picture is differ to normal picture, it can not render and create pictures animation in normal technique. This thesis makes a generalized analysis and research on plant simulation theory of iteration function system (IFS) and L-system, the former takes iteration as a main characteristic, the latter takes parallelism as a main characteristic. Discussion of fractal graphics rendering methods, and IFS fractals unique affine transformation algorithm. Simulation of the plant used "to change the mapping of various compression parameters or by adding random factors to get a new IFS parameters" approach. In the algorithm parameters of the introduction of a wind factor powf as a parameter, to a certain extent predict the wind factor on the extent of the impact of the trees sway, so as to prevent decision-making to provide a scientific basis for the typhoon,and thus resistance to the scientific guidance of the typhoon.In this article, the author tests with the VC++6.0, simulates the plant structure with the improved algorithm, and Displaying this picture in computer. Parameter values by adjusting the IFS, making the fractal tree in the original basis of static graphics achieve a better simulation effect.
