平移(translation)变换是几何变换中最简单的一种。初始坐标为(x0,y0)的点经过平移(tx,ty)(以向 右，向下为正方向)后，坐标变为(x1,y1)。这两点之间的关系是x1=x0+tx ，y1=y0+ty。 下面给出 Translation 的源代码。算法的思想是先将所有区域填成白色，然后找平移后显示 区域的左上角点(x0,y0) 和右下角点(x1,y1) ，分几种情况进行处理。

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。-Rag doll（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.-Rag doll (with the implementation of document)

数字识别，识别手写体。 使用神经网络算法编写。 识别率一般，带训练功能-Number recognizing system,used to recogize the hand writing figures.It is writen by nero network and has low recognizing effects but we can exercise it.

地图中等值线的识别与矢量化，可以实现从栅格地图（目前支持bmp,emf等文件）中获取等值线.GIS工程有用的。-contour map of identification and vectorization, can be achieved from the raster maps (currently supports bmp, catalog, etc.) access contours. GIS projects useful.
