Fractal-based Simulation Of Natural Scenes

Analog nature of computer graphics,research is an important topic.Naturein the form of random and irregular nature of the conventionalmethod canhardly be described.70s B.Mandelbort fractal concept proposed,as an emerging cross-disciplinary,non-linear by a wide range of academic importance.The main description of fractal theory of nonlinear systems in nature and not smooth and irregular geometry.So ups and downs of the mountains,floating clouds,vegetation,different forms of a variety of natural landscapes are the main description of the fractal object, and with our daily lives.Although the nature of plant species in many different forms,but are self-similar,self-reproduction characteristics of the fractal.In recent years,with fractal research and development,natural scene simulation research has become a hot issue.At present,based on fractal theory of plant simulation main L-system,IFS (Iterated Function System),particle system and the DLA model.In this paper,fractal theory in two parts on the snow scene of trees and the associated changes in the study done.First introduced in the plant than the popular simulation of L-systems and IFS(Iterated Function System),and L-systems and IFS(Iterated Function System) algorithm to achieve the research,and in close connection with the implementation of improvement, the algorithm to achieve a more simple and more natural description of the image.The article then the application of a particle system snow scene more real,and a variety of factors as changes in the ground by a series of changes took place.Texture mapping to enhance the use of realistic scenarios,effectively enhanced the real-time scene rendering and fidelity. At the same time,this article also uses the standard OpenGL graphics software interface and support for visual programming of the Integrated Development Environment VC++ to achieve a system based on improved methods and systems for static simulation of plants and the use of texture mapping and then by adding white noise of lively descriptions of natural scenes in the process of snow and snow.
