Three-dimentional visual design of rural buildings based on OpenGL

The impacting action of flood destroyed dramatically the buildings, which caused the vast people and economic losses. It is important to analyze and design the rural buildings to resist the flood. In this paper, considering basic characteristics of rural building structures, the three dimensional models of rural building were built, with the help of windows operating system, MFC framework of VC++ and OpenGL graphics technology, during this process the parameters were input by parameter dialog box. And then the three dimensional model under flood impacting was displayed to show the physical variables of rural housing construction. The drawing of the model on the screen can be scaled, so a friendly Man-computer interactive interface can come true with changing the interactive observation position in 3D space. It is proper to analyze directly and generate the simulation model of rural buildings, and convenient for analyzing and designing software of flood acting on rural buildings.
