Application of the network multimedia extension topology algorithm in wisdom sharing of the English teachers' scientific research platform is studied in the paper. In order to correctly read the original data of the STL model, better use the OpenGL technology to display the three-dimensional graphics, and realize its operation, we must understand its structure on the basis of fully understanding the STL file. This optimization also serve as the basis of the platform design. Specifically, the implementation process of the algorithm itself cannot increase the network traffic too much, and at the same time, it should also try to minimize the time required for discovery, otherwise it will then affect the performance and efficiency of the network as a whole. Then, we use the network multimedia extension topology algorithm to handle this challenge. Furthermore, the English teachers' scientific research platform is designed and tested based on this model.
