摘　　要：大型三维场景模型在虚拟现实中有着广泛而重要的应用。就此主要讨论了层次细节技术和基于网格的模型简化技术并提出一种改进的基于面片消减的移动立方体简化算法,从而有效的对建立的模型进行了简化和绘制加速。The large-scale three dimension scene has its important and wide-range application background in virtual reahty. This thesis pays more attention to introduce the level of detail （LOD） and mesh simplification for model simplification study . Except for those two technologies, it has made the improvement to original marching cubes by using patch diminution technology, which made the mode more simplified and quick.
