JDK1.4 提供的无阻塞 I/O（NIO）有效解决了多线程服务器存在的线程开销问题，但在使用上略显得复杂一些。许多基于 NIO 的多线程服务器程序往往直接基于选择器（Selector）的 Reactor 模式实现。这种简单的事件机制对于较复杂的服务器应用，显然缺乏扩展性和可维护性， 而且缺乏直观清晰的结构层次。本文将通过一个基于事件回调的 NIO 多线程服务器的设计，试图提供一个简洁、直观、易于扩展的 NIO 多线程服务器模型。

可以简化obj，ply等三维模型，1:在VC++2008上运行oglpemsh.dsw 文件 2:选择要简化的模型，eg:huge_bunny.ply 3:选择简化 (Mesh Simplification Viewer This program implements four different mesh simplification algorithms. After loading a mesh, the user can easily remove triangles from the mesh and the results are displayed in real time. The mesh can also be rotated and moved closer to or farther away from the viewer. The goal of mesh simplification is to display a 3D polygonal mesh with fewer triangles while retaining the same shape. In the example above, the original cow model (upper left) is made up of over 5800 triangles. We can easily remove thousands of triangles from this mesh and still display a very similar cow model. While the 500 triangle cow is a cruder representation, this may not make a difference if the cow is far away from the viewer. )
