I have a question about the algorithm of blur.
When I ping pong between buffers, it seems that something is wrong about the blur functionality, because with the various number of ping pong between buffers and having a deeper blur, the progress of blur is not what it should be, I mean the blur picture in 25 times blur is not that different from 35 times blur!
And you can see from the picture attached what I mean exactly, upper left picture is blur 5 time, upper right is 30 times, and downer left is 60 times and down right is 300 times!
Any idea or suggestions??
Any help appreciated prior
Regards
