directX使用HLSL实现每像素光照和每顶点光照，包含FX文件以及程序加载使用-The implement of per-pixel lighting and per-vertex light in DirectX with HLSL.

3D灰度图地形实现，通过对灰度图每像素颜色值的计算，实现3D场景的草原，山地，沙漠等地形-3D grayscale terrain to achieve, through the grayscale per pixel color value calculation, the realization of 3D scenes of prairie, mountain, desert terrain, etc.

Per_Pixel_Lighting Per-pixel lighting is commonly used with other computer graphics techniques to help improve render quality, including bump mapping, specularity, phong shading, and shadow volumes.
