I have a question about the popular FXAA shaders that are out there written using GLSL or HLSL, such as:


They mainly feature these three parameters:

#define FXAA_REDUCE_MIN (1.0 / 128.0) //0.0078125
#define FXAA_REDUCE_MUL (1.0 / 8.0) //0.125
#define FXAA_SPAN_MAX 8.0

I looked all over the Internet, but could not find a proper explanation about the function of each parameter. Can anyone help?
