it was a great time but no longer maintainable by c.Kleinhuis contact him for any data retrieval,
thanks and see you perhaps in 10 years again

3 Layers



http://www.fractalforums.com/index.php?action=gallery;sa=view;id=19694

3 Layer Mandelbrot:
0. Black background
1. Yellow for first pattern layer, lines from the left needle of the main Mandelbrot.
2. Blue for second pattern, as the result of a close passage in the seahorse valley of a minibrot
3. White, as the result of a close passage in the seahorse valley of another minibrot

Wow looks good!  How do you pick the distances at which to change colours?  I experimented with histograms but couldn't get any clues where to pick the levels (see attached).  I guess it's manual aesthetic choice?

I took your location, rendered it as raw floating point distance estimate, fed it through histogram equalisation and used it as depth (and brightness) for a 3D stereo (anaglyph red left eye, green right eye).  Here the perceptual layers just come out of the histogram equalisation, but there's not much control over relative depth (just a pow function to push them to one end or the other).

neat!  i was gonna look into anaglyph rendering at some point too.  i need to invest in a 5$ pair of solid glasses sometime... these paper freebies leave something to be desired  grin

<Quoted Image Removed>

Yes it is tweaked for aesthetic, but there is a real connection, as your image shows, between the influence from the close passage of minibrots.
Attached is the palette used.
Addition: Perhaps if log is used instead of sqrt, the colors of the palette could have equal sizes...
