Research And Application Of Fractal Image In CAID

The application of the fractal theory in computer graphic design can only draw some general fractal graphic. It can not draw the fractal graphic by using some graphic design software. And it is hard to describe the beauty of natural.The study focused on the method of drawing fractal graphics by using computer and the application of fractal graphic in CAID(Computer Aided Industry Design).It took advantage of Visual C++ 6.0 in the better user interface and programming technology;the paper can realize the software of drawing fractal images. In virtue of the knowledge related to fractal theory,it has already been realized on computer to draw some fractal graphics,such as Newton iteration fractal graphics,Mandelbrot set,Julia set and so on. Meanwhile,the fractal image can be mapped on a surface of 3D model,by the color texture mapping algorithm. Using the fractal theory to the device of computer graphic, it can not only draw many beautiful fractal graphic but also can offer the width space of device graphic for the device of advertisement,the decoration of house.Based on the analyses and research the arithmetic of escape-time and Newton iteration,this article redefined the escape time function and provides the accelerated escape time algorithm. Through a great lot data validation,keeping the aboriginal-precision,this algorithm makes the efficiency increase prominently. Then,this article gives several fractal patterns that are applied to product design by analyzing and researching the arithmetic of color rendering. And many beautiful and colorful fractal pictures are worked out to apply on product design by the new method of rendering. Also it offer the width space of art design.
