{"version":"1.0","type":"rich","title":"Fractal contour","description":"Inspired by https:\/\/youtu.be\/-RdOwhmqP5s\r\nIt can render the Mandelbrot and so much more! \r\nCreate your own fractals in the fz() and dfz() (derivative) functions.\r\nThere are several known issues that make this implementation mathematically inaccurate... For starters, it's supposed to use the polynomial roots as targets, but I'm using a fixed grid instead.\r\nI'm also using a sort of marching squares approach to get the contour of all slices in a single pass.","author_name":"llemarie","author_url":"https:\/\/turtletoy.net\/user\/llemarie","provider_name":"Turtletoy","provider_url":"https:\/\/turtletoy.net\/","license":{"fullName":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International","shortName":"CC BY-NC-SA 4.0","url":"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/4.0\/"},"thumbnail_url":"https:\/\/turtletoy.net\/thumbnail\/765d77abf4.jpg","thumbnail_width":512,"thumbnail_height":512,"html":"<iframe src=\"https:\/\/turtletoy.net\/embed\/765d77abf4\" width=\"1025px\" height=\"554px\" style=\"max-width: 100%; border: 0\" sandbox=\"allow-scripts allow-top-navigation allow-top-navigation-by-user-activation allow-forms allow-popups allow-same-origin\"><\/iframe>","width":1025,"height":554}
