说明：  水面反射和折射,提供源代码,通过下面几步实现: 1.设定一个附加裁减平面 2. 并把摄像机位置设置到当然视点对称的位置, 渲染平面以上部分到一个纹理. 3. 将反射平面的顶点传入VS, 并乘以投影矩阵.得到平面投影点的坐标. 4. 将上述插值传入PS, 并同时除以W, 并(projCoord+1.0f)*0.5f. 5. 再查询渲染得到的纹理, 并加入点噪声, 有水波纹的效果.
(surface reflection and refraction, providing source code, to achieve the adoption of the following steps : 1. Additional reductions set a planar 2. and installed cameras to the course Perspective symmetrical position, play up to the plane over part of a texture. 3. will be the culmination of reflection plane came VS. and multiplied by the projection matrix. be planar projection coordinates of points. 4. Interpolation of the above into PS, and at the same time divided by W, and (projCoord 1.0f)* 0.5f. 5. further inquiries exaggerate the texture, and point to noise, water ripple effects.)
