Opengl Implementation Road Alignment 3d Animation Technology

The main target of this thesis is establishing a project to solve the animation of roadway'shape,with the technology of OpenGL, and how to achieve the aim.The function of animating roadway'shape is very important part of road CAD system. The method being brought up in this thesis is utilizing the DXF file of 3D model, which is made by other CAD system, withdrawing the file in animation system, and achieving the animation of roadway'shape.The function of the software is realized in Windows operating system , utilizing VC language with the support of OpenGL. The main achievement of the thesis can be summarized as follows:1. Withdrawing the file of DXF in the system.2. Establishing 3D scene with OpenGL support.3. Realizing the animation of roadway's shape.4.Finishing the method of human_computer interaction.
