#### Angle based colouring

« on: December 08, 2019, 11:45:03 AM »
Playing with a different method to colour the Mandelbrot using KF data.
Using the angle to the Mandelbrot to choose a colour.  (A variation on distance estimation)

(Note: I've made my After Effect plug-in available for free if you want to try it for yourself.  (but you'd need to own AE)  https://www.maths.town/after-effects-plugins/kfmoviemaker)

Cool

Great
Can you describe algorithm in simple words and pseudocode ?
Like for example:

roughly speaking the code is

For each pixel:
x = average change in iteration count of pixels to left and right.
y = average change in iteration count above and below.
colourIndex = atan2(x,y)
