Based On The Opengl 3d Scene Visualization And Realization

With the development of computer visualization technology, the field of computer visualization applications continues to expand, not only used in scientific computing, industrial control, communications, artificial intelligence, and applications in entertainment, simulation and three-dimensional graphic production. Visualization is a hot area of computer technology. The cores of the hot areas are concentrated in the three-dimensional rendering realistic images on this issue. OpenGL is a software interface to graphics hardware, because of its portability, efficiency and practicality, in fact, it has become the industry standard in three-dimensional graphics built field.In this paper, visualization techniques for a brief overview, introduce the development of visualization technology at home and abroad in recent years. OpenGL programming techniques introduced in the Windows environment and OpenGL graphics rendering process. The starting point for research OpenGL, with the help of Visual C++tools for the visualization of three-dimensional scene to simulate three-dimensional terrain, sky, cloud, car, etc. With examples in the form, design and implement a car driving scene system. Three-dimensional scene visualization of two methods, random interpolation scene of analog and digital scene simulation, and two algorithms were used to achieve a realistic three-dimensional visualization of the scene. Highlighted Delaunay triangulation algorithm, by using the algorithm of texture mapping with OpenGL on computer features a fast and efficient rendering. Improved Delaunay triangulation and its in-depth comparative study, the experiment proved a more realistic three-dimensional simulation of the future scene has certain significance.Texture mapping using OpenGL technology provided by the sky, terrain, trees, street lights and other visual. Implement a vehicle traveling on the scene OpenGL visualization system that can simulate realistic car driving scene. It can reflect the physical movement of motor cars, and changing the calculation method and vehicle parameters, without changing the mapping procedures, and can be easily achieved under different vehicle parameters of a vehicle traveling on the visualization. It can be useful in visualization for achieving the real scene games and simulation.
