该程序是用DirectX技术使用纹理贴图实现了海浪的效果。该程序是在一个矩形表面应用纹理贴图表示海面，通过不断改变海面矩形顶点的纹理坐标，实现海浪动画效果。-The program is the use of texture mapping DirectX technology to achieve the effect of the waves. The program is in a rectangular surface texture mapping applications, said

用来研究Direct3D8的贴图坐标。本程序较简单。-Direct3D8 used to study the texture coordinates. This procedure is relatively simple.

d3d坐标变换习作，无贴图。旋转平台上可以控制物体移动。-d3d9 transform.
