Subject: Re: (fractint) Par Problem - Can you help?
Hi Peter,
Of course we can't tell what your images were supposed to be without
the GIF files. But two of your pars seem to be off the interesting part
of the image. Not sure what the problem is....
I zoomed back and panned to get these:

This might be a time to ask Tim what his view would be on posting
uuencoded gifs to the list. I am thinking of very small ones, with
viewwindows at about 10. Depending on the complexity of the image, these
would be around 10K or less. In cases like Peter's Turnz and Coilz, this
might be the only way to show what was aimed at, and indeed, if Peter can
re-generate Turnz and Coilz in the small size, it may help others to
figure out what is going wrong.
Unless and until Tim says, we should not post any such gifs to the list,
but it is something to consider.
Peter,
If you can generate Turnz and Coilz in very small size, I'd like to see
them and you could send them directly to me.

For various reasons, the consensus was in past discussions to put the
image on a web page and post a URL rather than sending the image directly.

We should put these on a web page. It would be an extra step, email
an attachment to me or someone else with room on a page. Then in
a day or so it would be up and referenceable.

I recommend no gifs to the list... there are about 25% on this list that
would be upset.
I have little room now with the contest but if I redirect the three winner
images
to Paul Lee's page, there is about 1 Meg at my geocities site.
I have been thinking of posting some of the hard to transfer par and frm
files from this list on my site in zip form, so that some who have even
more difficulty getting them to work than I can get them easily. The
digest does not help in this, since the difficulties often mean editing the
files as posted.
Geocities is free, so if any of you 'out there' want to get a page....
It is rather easy if you have a PC, Win95, and Netscape (not Explorer!!).
Dunno about other platforms.

^^^^^^^^^^^^^^
I'd like to comment on this, although it's only peripherally on-topic. I
assume what you're referring to here is GeoCities' EZ-upload facility,
where they state that it doesn't work with Internet Explorer. (For you who
have never used GeoCities, the "EZ" here definitely applies: it makes
uploading files for your GeoCities web pages *very* easy.)
Although Internet Explorer 3 does not work with this utility, version 4
*does*. So if you're using MSIE4, don't let that "Netscape only" bit scare
you away from using GeoCities. They'll give you 3M of space for free, but
they'll insist on ads in your pages. If you pay them $5/month, they'll
give you 15M of space and allow you to dispense with the ads.

Another peripheral comment
I have two sites at Geocities myself.....<<sigh>>. You can get a site for
every email place you have...I have two providers (god forbid I should be
off the net for ONE second!!!)
I use ws_ftp95.exe to upload to Geocities and my other 3 sites (I know...I
know...I'm wierd) which is a great program and extremely easy to learn and
set up. It's available for free at www.nonags.com...THE place to find cool
freebies. One warning......Microsoft Front Page and Geocities don't
mix....so use another html editor. If you've never done a homepage I have
a page devoted to the absolute basics of homepage making at

Well, I, at any rate, have got some problems with some of the sexual
innuendo, etc., posted to this list recently. I believe there are plenty of
chat groups on the net to satisfy this sort of need. And if by chance you
want the real thing -- why don't you check out
alt.binaries.pictures.fractals? Jerks are posting porn ads there all the
time apparently. Gynecological fractals, indeed. Get a life.

My sympathies......innuendo can be disconcerting.....but I'm sure you can
avoid all this stuff by merely deleting the emails with biological topics.
No need at all to sully yourself. Innuendo...like beauty...is in the eye of

I hacked a little M-set program to do this and the results are fairly
interesting from this first experiment... the possibilities are
endless....

Rich,
- Here's a quickie idea... use the last iterate of each pixel to generate
- texture coordinates (u,v) and then color the pixel by texture lookup.
Kai's Fractal Explorer (part of Kai's Power Tools) has an option to do this
sort of thing. It uses the potential for one axis and field line angle for
the other. Very interesting, but not as spiffy as one might expect. My
main complaint is its field line resolution is limited, and becomes pretty
much worthless after a few zooms.

Hi Rich,
If you could explain to this forum how to specify the color of a pixel,
given most any other information about the point in question, it would
be a first. I have asked several times. I have some neato schemes
I code in C++ for my clunky Borland C++ 3.1 with slight graphics
support. (See DEEPZOOM for example, on my Geocities web page)
So I know c, z, iter and some other info which is special. Now how do
we specify color. Remember, I still want to use Fractint's other support
such as period checking, escape detection etc.

Sorry, but you can't (yet) do it in fractint. However, the topic of
using information from the iteration to give extra inputs to 24-bit
coloring algorithms has been discussed here at length. I've proposed
replacing fractint's current "color = iteration" paradigm with the
idea of being able to write formulas to generate the color at each
pixel. I think this is doable, but I don't really have any
environment in which I can compile 16-bit DOS apps to be able to add
this kind of support to fractint myself. I think it will have to wait
until fractint is 32-bit app friendly or until I do more work on
hacking xfractint to work (stymied at every turn! :) properly in the
environments available to me.
Suffice to say that this particular kind of coloring is something
like:
u = 1.0 + real(z)/|z|;
v = 1.0 + imag(z)/|z|;
color = texture[u][v];
To give you an idea of how it looks, take a peek at

Jay,
- If you could explain to this forum how to specify the color of a pixel,
- given most any other information about the point in question, it would
- be a first. I have asked several times. I have some neato schemes
- I code in C++ for my clunky Borland C++ 3.1 with slight graphics
- support.
If you only want to specify a color index, you can see the example FRMs
posted here by Kerry Mitchell, Paul Carlson, and myself. These show how to
write FRMs that use ordinary fractal types with new coloring techniques.
The one I posted has over 100 formulae Since you can do this with FRMs,
you get to use periodicity checking, solid guessing, or whatever.
Of course, this only gets you as far as specifying the color index; you
can't hard-code the palette into the FRM, and right now FractInt is still a
256-color beast. I have had good results rendering the same point with
different coloring methods, using entirely different palettes, and merging
them together with a graphics package.
