Mary,
I am new to the Fractint list also - although I wrote a lot of
programs to create fractals back when the graphics
adapters commonly had a resolution of 320 x 200 with
16 colors! I am enjoying getting back to creating
fractal images using Fractint.
I liked your picture in the M-set very much. It has a nice
Julia set-like quality to it. I especially liked your color map.
It is very sophisticated - despite its apparent simplicity.
How did you make it? One unusual aspect of your image
and color map is that the mostly red outside edge of the
'island' of your image is adjacent to a blue
surrounding field. Due to the fact that the eye focuses
different colors at different depths in the eye, the 'island'
in your image appears to hover 'above' (closer to your
eye) than the blue surround. You have created a truly
three dimensional image - as far as the eye is concerned!
(This effect is enhanced somewhat if the room you view
the image in is darkened and direct your gaze to the boundary
between the red and blue. When the effect appears I can
then refocus my attention to the entire island and it will
remain hovering above the blue 'background'. )
Did you construct your color map in order to create this effect?
Please let me know whether you are able to see this effect.
Would others who create your image please let me know whether
they can see this as well? Thanks
I zoomed into the center of your image on the miniature
mandelbrot set located there (Jim Muth calls this
a 'Midget') and created another image using your
color map. The file to create it follows. The image takes
about 3-4 hours on a P400 using the 1024 x 768 x 256
disk video mode. (My Windows 98 machine actually
uses Expanded Memory instead of the disk.) I increased
the maxiter to 10,000 to insure an accurate coastline
to the mini-brot. I don't believe that the high maxiter is the
cause of the long creation time. I believe it is because
in most of the image the actual number of iterations it
takes to color the pixel is large. Also,
periodicity testing inside the 'lake' of the M-set should
keep the number of iterations from reaching 10,000 there.
[Can anyone confirm those two conjectures?]
The 'island' in my image resembles a starfish with eight
arms. Just within it is the outline of another 'starfish' with
16 arms. Within it is one with 32 arms, etc. I can just begin
to make out some of the arms of the starfish with 256 arms
with the image rendered at 1024 x 768. I don't recall being
able to see a period doubling of that high an order before -
and I look every time I see this doubling in a minibrot.
I believe that Guy's expression in his message to you:
"...a more performant version of FractInt..."
means that it will create images more quickly. :-)
