Creating Custom Color Gradients
- Choose a palette depth of 4, 8, 12 or 16 colors.
- Choose a gradient depth of 16, 32, 64, 128, 256 or 512 levels.
- Choose the color interpolation method ('None' or 'Linear').
- Create the palette by picking colors using the color picker widget and applying the selection to each
palette slot in turn.
- Click 'PAINT'. A color gradient will be created dynamically and applied to the displayed fractal.
- The custom color gradient will also be added to the list of available color rendering themes in the format
'User_x_nnn', where 'x' is an auto-incremented number and 'nnn' is the number of levels.
Navigating Mandelbrot and Julia Sets
The Mandelbrot set can be considered a map to an infinite number of Julia sets. Pressing
Alt(Option) + Click or at various points around the
Mandelbrot set (or its variants) produces a variety of
Julia sets. The most interesting images can be found just outside the perimeter of the Mandelbrot set.
Mandelbrot variants like the so-called 'Burning Ship' can map to extraordinarily beautiful Julia sets.
Julia sets can be 'rotated' about their origin by applying a polar rotation transformation to the
complex coordinate c in the equation z = zⁿ + c. By successively incrementing the rotation angle by pressing
the button, a 'spinning Julia' animation can be
produced.
The frame rate or speed of rotation is governed by the 'Spin Inc' setting; smaller values produce slower and
more intricate rotations.
