该算法用帧间差分法将帧中的背景象素点检测出来,再确立出背景帧;由于排除了帧中运动物体的影响,因而提取出的背景干净,效果很好,然后运用背景差分检测出场景中的物体，结果表明,该方法快速有效,能够满足实时性的要求

动态绘图类源码，可以动态的绘制不通的曲线，且实时显示-dynamic mapping source category, dynamically mapping unjustifiable curve, and real-time display

Ageia s PhysX(著名的游戏物理库) D3D 9使用代码演示。由于PhysX物理库使用OpenGL代码实现图形着色，从而使许多用DirectX 3D的程序员不能使用/读懂demo代码，这是使用D3D着色引擎重新写的一些demo代码。-Triangle Mesh（带执行文件）-Ageia s PhysX (well-known game physics library) D3D 9 demo using the code. PhysX physics library as a result of the use of OpenGL graphics rendering code so that many use the DirectX 3D programmer can not use/read demo code, which is the use of D3D shaders to re-write some demo code.-Triangle Mesh (with the implementation of document)
