I wrote a bit of POV scene code to help explore Mandelbrots. The
source is at the end of this message.
The helpful part is the macro defined at the very beginning; it centers
the view around a particular point, so that there is no need to use
guess work. Simply render, select a spot worthy of further magnification,
add in code using the Center() macro, and then add a scale transform to
zoom in.
You can also tweak the color map and the frequency setting to get a
pleasant combination of colors.
Enjoy,
John
