Three-dimensional models can better express the internal structure of cells. In the field of virtual education we can have an interactive operation so that learners will have a visual and perceptual understanding, thus master the knowledge more easily. we use VS tools , OGRE engine to complete reading and reproducing 3DMAX models. As for Three-dimensional modeling with large volumes of data, we used the level of detail (Level Of Details) algorithm, to delete unnecessary edges, lines, planes, and some texture mapping, reducing the data volume to the scope that can be accommodated. As for the texture that can be reused we use the local feature extraction, a study which has a great significance on the research of lightweight modeling.
