计算单应矩阵，输入为2D图像坐标点和3D世界坐标点，输出为3x3单应矩阵(Calculate homography)

游戏以全3D效果进行画面展示，第一视角制作，场景多变恢宏，从室内至海滨各有不同景色，惊显该款游戏拥有的无穷魅力。 在冲浪过程中：不但可以体会加速，转弯，翻腾，还有更多精彩动作。这样经典的一款手游巨作，(Games in full 3D effect screen display, making the first perspective, magnificent and varied scenes, from the interior to the seaside are different views were scared that the game has a charm. In the surfing process: not only can experience acceleration, cornering, somersault, and many more exciting action. Such a classic hand travel giant, so what, now experience it ......)

这是微软Win8 上宣布放弃Mirror driver之后推荐采用的抓屏技术， 全部基于D3D/DXGI技术， 效率非常高， 并且包含变化区域和屏幕鼠标光标。它的缺点是没法抓取某个窗口的内容 。(This is a renounced Mirror driver after Microsoft Win8 recommended screen capture technology, all based D3D/DXGI technology, efficiency is very high, and contains changes in the regional and screen mouse cursor. The disadvantage is that the contents of a window can not crawl.)
