Diffuse particle trails when you "accidentally" allow some of your blur filter weights to go negative
Diffusion pattern particle trails with only subtle tweaks to the weighting coefficients. The trails continue to edit the pattern.
@scdollins That's pretty cool. It looks like the results you get by repeatedly applying an image sharpening operation.
@Metamere That's effectively what it is. Mid-way between a blur and a sharpen. It only takes a subtle tweak to the filter radius to tip it more from one to the other.
@scdollins Nice! In some of my earliest #GenerativeArt experiments, I used an image editing program called Irfanview to repeatedly manually apply sharpen, blur, crop, and resize. It seems that using shaders would be an efficient way to re-explore that technique.
