Hi,
I’ve just started playing around with snapshots in graphics 2.0 and pretty much got them working as I would like! One effect I’m playing around with is to have a snapshot blur out to nothing. Rather then applying a gaussian blur with increasing blur radii, I was wondering if it’s possible to repeatedly apply a blur to the same snapshot again and and again, so that the blurred image is written back to the snapshot? I guess like a feedback loop in audio?
Thanks,
Yes you can, you need to do double buffering. I detailled how it would work here:

Do note that the document is now out of date, as the first part was tweaked for an article.
But the bits further down the document, detailing double buffering is what you’d want. It isn’t the simplest of thing to understand, but it does work.
Cool! Thanks for that! That document is a great help, thanks for the examples too!
