vb+opengl建立的机械制图虚拟模型库，可以网络更新模型库，实现了模型的操作-vb+ opengl established mechanical drawing a virtual model library, you can network update the model library to realize the operation of the model

一个关于复合三维模型控制的案例源代码，网络游戏-Complex three-dimensional model case of source code control

基于小波神经网络辨识的PID神经模型源程序,不错的源码 很好-The PID neural model based on wavelet neural network to identify the source program, a good source is very good
