Realistic graphics generated geometric objects is an important part of computer graphics . For natural objects , due to its irregular , can not the traditional Euclidean write accurate equation in geometric modeling process , usually only Approximation . Fractal geometry is another way , it is inherent in irregular start from the natural object , looking for the \. Fractional Brownian motion FBM fractal geometry , which allows you to build a the highly fractal characteristics of three - dimensional geometric model , the geometric model can be used to generate a variety of different natural objects , such as mountains , clouds and realistic graphics . Midpoint offset method is an important method of generating fractal Brownian motion , it uses recursive and iterative implementation mode, the computer is the longest in the completion . VC 6.0 provides a full-featured , easy-to- application development platform , and OpenGL as a powerful , portable 3D application programming interface ( 3D API ) , has become an indispensable tool for natural object data model visualization . This paper gives a complete way of a midpoint offset method to generate three-dimensional geometric model of the mountains, clouds and other natural objects , and VC 6.0 development environment , by means of OpenGL to achieve the visualization to generate a realistic mountains and clouds graphics.
