Fractals are abstract mathematical sets, and there are multiple methods to render them. I have some examples based on the “chaos game” and some based on the escape time algorithm.
To teach myself about webGL frame buffers and rendering to off screen targets, I wanted to try out rendering based on repeatedly rendering the entire image and merging it through each of the functions. It works well for subjects in the center of the screen, but it breaks down quickly as portions of the set stray off screen, which makes it tough to use as a general purpose renderer.
