GL to OSL, random pattern from glslsandbox.com 

Are you thinking about something like making your own blur kernel? There are several ways to go about that, actually last night I did a fibonachi convert from GL to OSL works great, but also box kernel and gaussians are possible.

@@madsdrschler7853 There are so many interesting possibilities. I am stuck at the point of sampling the input image many times. I will try again this evening.

@@weightednormal3682 typically you sample something multiple times in a for loop. pastebin.pl/view/e053c3c6 here is the fibbonachi blur.

@@weightednormal3682 for(float i = 0. ; i < samples ; i++) { vec2 offset = phyllotaxis(i, samples) * radius; vec2 tt = uv+offset; col += texture(tex, tt.x,1-tt.y); }
