Title: Tricorn and Mandelbrot Post by: element90 on September 23, 2011, 03:21:30 PM Tricorn and Mandelbrot (http://nocache-nocookies.digitalgott.com/gallery/8/5522_23_09_11_3_21_29.jpeg) http://www.fractalforums.com/index.php?action=gallery;sa=view;id=8689 One of the side effects of using the "circle fold in" transform with the standard Mandelbrot formula the the appearance of tricorn islands in addition to the usual Mandelbrot islands. Parameters Formula: Mandelbrot z = transform(z) z = z^2 + c Number of A Transforms: 0 Number of B Transforms: 2 Transform 1: translation, -0.1 Transform 2: circle fold in, diameter 3 centred at 0 + 0i Transform Squence: ABA Complex plane transform: none Initial values of z: c Image centre: -1.86552 - 0i Long side: 0.237227 Rotation about image centre: 0 degrees Bailout condition: norm(z) > 16 Maximum iterations: 100 Colour selection: outer for bailout otherwise inner Outer colouring: minimum change in magnitude Inner colouring: fractal dimension of magnitude Programs: saturn and titan |
