The Building Of The3D Model And Simulation For The Tunnel

In this paper, we obtain the three-dimensional simulation of the tunnel by use of the VC++development platform and OpenGL software interface. In chapter two, we introduce some basic theory for this paper, i.e. the Rational B-Spline method、golden section method and realistic graphics technology. In chapter three, we introduce the principle of3D modeling, furthermore, we analyze structure of the tunnel model. In chapter four and chapter five we give detailed steps and the mapping implementation of the design for tunnel and cross channel model. In chapter six, we introduce the method of improving3D simulation efficiency,mainly the texture mapping technique and the pixel mapping technique,as applications of these techniques,we improve greatly the speed and the effect of the3D simulation. In the last chapter, taking multi-arch tunnel for example,we give a3D simulation graph of the tunnel.
