摘要：
RHW(Reciprocal-of-homogenous-w)RHW坐标是告诉D3D顶点序列已经经过3D变换，不需要在由D3D进行世界变换学习D3D9的时候遇到灵活顶点格式(FVF)中D3DFVF_XYZRHW和D3DFVF_XYZ之间差异而引起的问题。参看了同是C++博客的一篇博文,其分析如下:The RHW value, which stands for Reciprocal of Homogeneous W[1], tells Direct3D that the vertices that are being used are already in screen coordinates. 阅读全文
