GLSL-一遍高斯模糊
可以实现片段着色器进行一次高斯模糊吗?我发现很多两遍模糊(高斯和盒子模糊)的实现: http://callumhay.blogspot.com/2010/09/gaussian-blur-shader-glsl.html http://www.gamerendering.com/2008/10/11/gaussian-blur-filter-shader/ http://www.geeks3d.com/20100909/shader-library-gaussian-blur-post-processing-filter-in-glsl/ 等等。 我一直在考虑将高斯模糊实现为卷积(实际上是卷积,上面的示例只是近似): http://en.wikipedia.org/wiki/Gaussian_blur
