The Mandelbrot set use this iteration formula:

z := z^2 + c;

where z is initally zero.

We color pixels corresponding to the value of c according to the
number of iterations, n, it takes to have |z|>2.  If n gets beyond
itermax we set the color to black, usually.

You control what part of the Mandelbrot set you see by how
you map c to the screen.  You use some interpolation formula
like

c(real) = c(left side) + column*deltac
c(imag)=c(top)-row*deltac


So your initial parameters are c(left side), c(top), deltac or an
equivalent set like the center c and magnification.

Hope this helps.

According to Damien, you only need 2Mb for 1600x1200x256 (thanks for
posting that formula Damien; I had forgotten it). Too bad your monitor
doesn't support it. This is my favorite mode for fractint.

Yes, that is correct. Unless, of course, you want to run other programs at
that resolution.

It only means that the video board that came with your system only supports
4MB. But you could replace that video board with another one (or if it is
built into the motherboard, you can disable it). I was just on Matrox's web
site and their new Millenium II comes with either 4Mb, 8Mb, or 16Mb! They
just lowered the price too. It is about $200 (US) for the 4Mb version. This
is a very good price!

Subject: (fractint) Video Cards

Hey gang,

Well I have let my post go for a few days concerning the Imagine 128 and
I guess nobody uses one.  So lets try another question:

If you had the oppertunity to get a new video card for drawing fractals,
what would it be?

I am also wondering if 3D accelerators can help in drawing any types of
fractals.

Any input would be appreciated as I've decided to upgrade my system
now.  The Imagine128 doesn't work with the new DirectX drivers for
windows games anyway...

Sincerely

Tim Maxwell

Hi.
Could someone please tell me what anti-aliasing means? I am under the
impression it has something to do with creating high-rez images and then
bringing them back down to a smaller size. I do this because they look
better than when I just create them at the smaller size, unless my eyes
deceive  me. Anyway, I am curious what people mean when they say they are
doing such and such a thing to their images for anti-aliasing.

                    Thanks,
                    Peter

Subject: Re: (fractint) video modes continued

Gedeon,

Your card should be able to do 1600x1200x256 with the 2M you currently
have.  You should also be aware that quite a few graphics cards will do a
1600x1200 VESA mode as interlaced, so your monitor only needs to be able to
handle half the vertical resolution (600).  Your monitor easily does this.
You'll just want to make sure you use the VESA modes in FractInt (which
work best under Win95 anyway).

Your *computer* will take an 8M graphics card fine.  Whether or not your
graphics card will take an 8M *upgrade* is another issue--one that only
your graphics card manufacturer can answer.  And it's solely dependent on
the graphics card; nothing in the computer or monitor affects this.

Subject: (fractint) Re: anti-aliasing

Peter,

Assuming you don't want a technical answer (which would only barely not be
over my head :) you can think of anti-aliasing as a way to smooth out rapid
transitions in an image.  Think of the highly detailed "mush" areas of a
fractal image--those areas would show more detail zoomed in, possibly even
resolving into structures you could see, but in your image they're just
"mush".  Well, anti-aliasing typically involves generating the image at a
higher resolution, to go ahead and resolve those areas... and then the
image is reduced in a graphics package, which averages several pixels down
into each pixel in the smaller image, giving the "overall" color.

This is a pretty bad explanation, but no doubt someone else will step in
and take the time to do it right. :)

Tim,

 - Well I have let my post go for a few days concerning the Imagine 128 and
 - I guess nobody uses one.

Well, I don't have one, didn't get one because some 64-bit cards were still
faster than the Imagine 128.  Seemed at the time that Number Nine was just
going for the "bigger is better" approach. :(

 - If you had the oppertunity to get a new video card for drawing fractals,
 - what would it be?

Well, that depends on whether you've got a system that can take PCI cards
or not.  I hope you do, because that makes it easy: any modern card will
do.  You'll be hard-pressed to find a new card with less than 2M, which as
I've described is more than adequate for all but the most die-hard FractInt
fanatics with 21" monitors.  (And oh, would I love to join the ranks of
those fanatics! :)  So buy your next graphics card, not for what it can do
for FractInt, but for what *else* it can do.  Personally, I'd lean towards
something with decent 3D acceleration, preferably with a Voodoo chipset
from 3Dfx, for awesome Quake/Hexen performance, but that's just me. :)

 - I am also wondering if 3D accelerators can help in drawing any types of
 - fractals.

Not in FractInt.  The only thing a 3D accelerator might help would be 3D
rendering of fractals, but keep in mind that 3D cards are typically
designed with real-time (read: low-quality) performance in mind.  If you're
generating images thirty times a second, you don't typically care that it's
not doing filtered interpolation with Phong-rendered highlights and proper
shadows... but if you're rendering a still image that people are going to
be gazing at for a long time to come, you want to make sure that it's done
right, because you may not get the chance to do it over.  3D cards don't
always accelerate final renders (depends on the renderer) but they can
certainly help out interactive editing of 3D objects.  But again, not in
FractInt as it currently stands.

 - Any input would be appreciated as I've decided to upgrade my system
 - now.  The Imagine128 doesn't work with the new DirectX drivers for
 - windows games anyway...

*Lots* of stuff doesn't work with DirectX yet.  My sound card, a Gravis
Ultrasound, has such lousy driver support that DirectX crashes most things
that try to use it.  That's why when I re-installed everything a couple of
months ago, I didn't install DirectX.  'Course, none of this is
FractInt-related... :)

anti-aliasing

<graphics> A technique used on a grey-scale or colour bitmap display
to make diagonal edges appear smoother by setting pixels near the edge
to intermediate colours according to where the edge crosses them.

The most common example is black characters on a white background.
Without anti-aliasing, diagonal edges appear jagged, like staircases,
which may be noticeable on a low resolution display. If the display
can show intermediate greys then anti-aliasing can be applied. A pixel
will be black if it is completely within the black area, or white if it
is completely outside the black area, or an intermediate shade of grey
according to the proportions of it which overlap the black and white
areas. The technique works similarly with other foreground and
background colours.

In a lot of graphic applications (like Adobe Photoshop), anti-aliasing
produces a smooth-edged selection by partially filling edge pixels so
that they are semitransparent.  Because anti-aliasing removes jagged
edges, it is especially useful when you=92re creating composite images by=

cutting and pasting.  No detail is lost, since only the edge pixels
change.

Anti-aliasing is a method of smoothing the edges of shapes, objects, and
mask selections.  Anti-aliasing creates intermediate pixels that smooth
the transition between colors and sharp edges.  To produce a curved or
diagonal edge on a selection, pixels in the image that are diagonal to
each other are part of the selection=92s edge.  This diagonal pixel
selection can produce a jagged edge.  Anti-aliasing makes some of the
pixels located along the inside edge of the selection semi-transparent
which smoothes out the edges of the selection.

Smoothing the jaggies in a bitmapped image. When diagonal or curved
lines are put in bitmapped form, these shapes must be made with square
pixels; any lines that are not vertical or horizontal have a
stair-stepped appearance. Anti-aliasing changes the pixels along the
edges of the line into varying shades of gray or in-between color, in
order to make the edge appear smoother. In a black-on-white image, for
example, the shade of gray used is determined by how much of the
in-between pixel overlaps the black area and how much overlaps the
white area.

[engage "bad explanation" mode :-) ]

The term "anti-aliasing" is most probably a throw-back to signal analysis,
and what happens when you take discrete samples of a continuous signal.
Essentially, if you think of a signal as a series of sine waves with
different frequencies superimposed, then you can only resolve certain
frequencies, dependent on your sampling frequency.  Frequencies higher
than the cutoff ("Nyquist frequency") get folded over and are seen as
lower frequencies.  Thus, the higer modes are "aliased" as lower modes.
So, anti-aliasing is a way to prevent this from happening--you filter your
incoming signal to remove the frequencies higher than the cutoff, then
sample it.

There are parallels to fractalizing.  The pixels of a fractal image
represent discrete samples of a continuous signal (mathematically pure
fractal).  The "jaggies" and "mush" that we commonly see are high
frequency (high spatial frequency = small, pixelwise) structures that are
sampled too poorly to be resolved.  In other words, the swirls and
midgets are too small to be captured by a "reasonable" number of pixels,
so they look like "mush" or visual noise.  Instead of pre-filtering the
fractal, we compute it at a higher resolution and average it down to a
lower resolution.  This has the effect of smoothing over the higher
frequencies, while leaving the lower ones (big structures) basically
untouched.

How's that?

Anti-aliasing is also used to get rid of Moire patterns, such as you see
if you raytrace a black green-gridded floor or one with green parallel
lines converging in the distance. Similarly for averaging out "busy" areas
of pictures. :)

One way I could think of, off the top of my head, would be to <s>ave your
fractal as a .gif file, and then printing it with your basic .gif viewer,
say your favorite Web Browser.  Just a thought.

I would forget all about trying to print directly from fractint.
Instead you should save you images in their native .gif format and then u=

a graphics package to print these. If you are running Windows, then I wou=

suggest starting with the shareware program "Paint Shop Pro" - it won't
cost you anything to try it!

For me, the most important key to getting a good looking print is to crea=
te
your images at very high resolutions. You could even use one of the
"disk/ram" video modes and save those images directly to disk. For *reall=
y*
big fractals you could use the "divide and conquer" method for creating
very large images in pieces (refer to fractint.doc).

As a rule of thumb, think of the dots from your printer as pixels in the
image. So, if you print a 10"x8" image at 300dpi, you could start with a
gif having dimensions of (10x300) x (8x300) or 3000x2400. If this seems a=

bit "over the top", then try printing from a 1600x1200 image for starters=

I can't duplicate either problem.

Your fractint.cfg file is corrupt. Try replacing it with the one in
the 19.6 distribution.

This is absolutely good advice. The fractint authors know very little
about printing, and have access to few printers. We can't even test
the printer drivers that are donated to our code. However, all is not
lost. There are many excellent programs that print GIFs, so the best
bet is simply to save the GIF and print it in other software.

When we have a windows port this problem will go away, but the DOS
version will always be print challenged. If Fractint were commercial,
we could simply my a library of printer drivers. But since Fractint
is free and we publish the source, we can't do that.

Tim

(This is absolutely good advice.) [Tim Wegner]

Mentioned this once: I have found it best to save the .gif to be printed.
It can then be imported into a word processing document such as
WordPerfect, Adobe Pagemaker, etc. by cut and paste or copy and paste.
After importing it the image may then be resized (if desired) for various
applications, such as a unique "logo" on stationery, for making a unique
greeting card, for address labels, envelopes, or even printing on transfer
paper to be transferred to "T" shirts, etc.

Depending on the graphics program .gifs are associated with in whatever
specific computer such as PaintShopPro, LViewPro, etc., other images can be
inserted into the fractal .gif (resized if necessary). That can make for
some unusual effects also...   :) or special effects can be added. This
last just as an added after-thought.

My fractint.cfg file is exactly the one that came with Fractint,
unmodified. To be exact it is the one from the .zip located at Spanky. Did
you try the Spanky .zip instead of your development version?
