Title: Seahorse spiral Post by: Duncan C on April 26, 2010, 04:15:29 AM Seahorse spiral (http://www.fractalforums.com/gallery/2/190_26_04_10_4_15_29.jpeg) http://www.fractalforums.com/index.php?action=gallery;sa=view;id=2181 A fairly typical Mandelbrot set spiral from Seahorse valley. This image was rendered using distance estimates to plot the neighborhood of the Mandelbrot set in black, and then using histogram-based coloring and fractional iteration values to plot the exterior in a gradient from white to red. I added a sinusoidal variation in brightness, which gives the red-white gradient a wavy look. Maximum iterations: 5000 Center Point (real, imaginary): -0.74519, 0.11267 i Plot Width (real): 0.00143 |
