Have you ever designed a fractal, only for there to be a hole in the centre you wish you could get rid of ? Quite often, especially with Julia transforms you will find this situation, you can (and if there’s an option) increase the dist value of the julia, but that doesn’t always look right. Here’s another way to fill in those holes. I can’t remember where I read this first, but credit to whomever suggested it as a solution. I’ll try to do a “how to” screenshot page at a later date, but for now, here’s the video. If you prefer a step by step guide, there is one here.
