摘要:: 在三维计算机研究中，三维数据的输入是个复杂的问题。大量的数据处理也会带来大的障碍，使得计算机速度较慢。不仅如此，这对于计算机辅助设计，以及计算机艺术等领域更会带来很多的不便。故针对以上问题文中提出了基于二维图像来进行三维的转换，从而得到三维图像效果，将复杂问题变得简单化。采用了四叉树分割技术对计算机输入的二维图形进行三维转挟，通过用这种方法找到二维图形的几何信息和拓扑信息进行几何造型，再将图形的结构信息输入给OpenGL，OpenGL对数据进行处理，通过投影变换将二维图形转换为三维图像

Abstract:: In the three- dimensional computer studles,the introduction of the three - dimensional data is a complicated problena, and a large amount of data processing can bring heavy obstacle that make speed of computer to be relatively slow. Moreover, this to CAD, and computer art, etc. field can bring a lot inconvenient even more. So directed against the question that the above appearing,a thesis has proposed carrying on three - dimensional eonversion on the basis of the two - dimensional picture, thus get the result of the 3 - D view, make the complicated problem to be simple. Carry on the technology that the two - dimension changes to the three - dimensional location pictttre that the computer inputs,the article puts forward a theory that quad tree set up split method,can make finding two- dimensional geometry message end topological message of figure carry on the modeling of geometry good, then input the structure information of figure to OpenGL, utilize OpenGL vary projection, show at the screen of the computer three- dimensional view of object that comes out
