What could be done is to use the FRACTINT INDEX at:
    http://spanky.triumf.ca/www/fractint/findex.html
to find pertinent information for a particular area.  Almost all of the
information necessary to use FractInt is available online at the
database.  The only thing that is missing is an easy way to search
through the website for all references to specific keywords.

May be we can talk Noel Giffin into adding the following code to one of
the "major" FractInt webpages at Spanky
_______________________________________________________________________
<TABLE BORDER="0" WIDTH="80%" CELLPADDING="5">

      </FONT>
    </TD>
  </TR>
</TABLE>
_______________________________________________________________________

Another possible solution is the use of the FRACTINT.DOC in a word
processor (such as Microsoft Word) that allows the creation of a table
of contents that sends one straight to the page in question, and/or use
of search/find functions.

I could create a Win-95 compatible Help file using the FRACTINT.DOC if
there was a demand for this by the FractInt Developers.  It would take
many hours of work (probably weeks) to get it fully functional with all
of the current data (or the new 2.0 data).  But then a quicker index and
search capability would be available than being on the web or using a
word processor.

Later,
P.N.L.

Subject: (fractint) Documentation search function

Hi to those having trouble searching the documentation:

Simply load the fractint.doc into your favourite word processor, I use 
wp5.1, and you have all the search and indexing function you would like.

I have a printed out version of the file as well since I  cannot get used to 
absorbing text from a screen as opposed to a book.  Very handy for 
making ones own annotations to the text, particularly in the vague areas.


Regards
Gordon

Indeed!  Many times I have insulted someone on email, completely
without intending to.  Sometimes email is a weird medium -- you think
you said what you meant pretty clearly, but the person who responds
obviously thinks it's clear you mean something completely different.

If you're dealing with reasonable people, this can often be corrected
by saying, "It sounds like you were trying to insult me.  Is that what
you meant?"  Or, "It sounds like you thought I was trying to insult
you.  That wasn't what I meant!" if you're on the other side.

Also, it's easy for your emotions to run high over email.

Well, it sounds like you haven't used Linux.  This situation is quite
typical of `open-source' software, where anyone can copy, modify, and
use the software freely.  Typically, the people who wrote the software
end up getting asked lots of questions over and over, so, being lazy,
they put the answers in the documentation in the next release so that
they won't get asked so much :)

Also, after you answer the same question in email three or four times,
you have a pretty decent manual page -- all you need to do is add it :)

The usual solution in the Linux world is to write HOWTO documents that
guide people through common tasks.  One HOWTO example -- on how to set
your Linux machine up to use Hebrew characters -- can be found at
<URL:http://sunsite.unc.edu/LDP/HOWTO/Hebrew-HOWTO.html>.

This way, when you want to know how to do something, you check to see
if there's a HOWTO that covers it -- and there usually is, since with
four to ten million Linux users, it's likely that thousands of people
have tried to do what you're trying to do, and some of them have
written about it -- and read the HOWTO.  But if you want to understand
how something works -- or if there's no HOWTO --, you look it up in the
reference manual and get a detailed explanation.

Also, FAQs are often helpful.

This happens to me often.  FAQs help some here, but a well-organized
manual and FAQ is most important in keeping this from happening.

The HOWTOs usually have exemplary organization -- you can usually read
them straight through, but they also have a well-defined (and usually
well-thought-out) hierarchical structure that lets you quickly find the
answer to a particular question.

Indeed.  (Folks: remember this next time you answer a question like
this!) :)

It's also caused by web-browser design problems.  I use Opera
(http://www.operasoftware.com/) which lets me turn off all those
annoying colors with a convenient button, and doesn't print backgrounds
by default.

Agreed -- to some extent.  If the artsy stuff actually makes it easier

In MS-Windoze, you can usually set your printer to print in
black-and-white from the Print dialog box.

Yeah, that's no fun.  I like Opera for this -- one quick button and
it's done.

Agreed!  *Everyone* (except web page designers) hates frames.  I
usually turn off frames support in Opera -- and when I have it turned
on, I usually use its `maximize frame' feature, which expands one frame
to fill the whole browser window.

In Netscape or MSIE, I usually unframe myself by opening links in a new
window -- in Netscape, you can do this by clicking on them with the
middle button, and in both of them, you can do this by right-clicking
on a link and selecting `open in new window'.

When Netscape first invented frames, they changed
http://home.netscape.com/ to be a frames page.  They got so many
complaints about it that they turned it back into a normal page.

> Bottom line. Keep It Simple on your study and reference sites.

Keeping it simple, if possible, is good for *any* web site.  (Although
pretty backgrounds are kind of neat sometimes.)

Subject: (fractint) my website

Hello fractineers!

Just a public annoucement about my website. I've been getting some e-mial 
regarding access to my website. My oh-so-wonderful school decided to charge 
all of its fellow students for their web space for web pages AND dialing up 
from home. It all used to be FREE. Considering what we all have to pay for 
tuition and odds and ends (that don't meet), we pay much more that 
expected. It used to be $10 a quarter for about 20 megs of web space. Then, 
to use my Institute of Technology(my specific college..a.k.a IT) account at 
school, I had to pay another $100 per quarter...plus they give me about 10 
more megs. I was kinda bummed out about that, but I got what I 
wanted.....mp3, pics, fractals, games.....you name it. And the best part 
was, I could download the files at around 50+ kilobytes per second, even up 
to 200Kbps. Whereas at home I was at 2-3Kbps.....ack!!!

Now, however, The school has decided to charge us EVEN MORE!!! They erased 
ALL old web pages so that they can use that room for something else and 
told us to move our pages to a new location on their network and pay MORE. 
I didn't read the price, but I can imagine it'll be 2-5 times more 
expensive than before and than other dial up charges to access it and the 
list goes on and on. You get the jist. So now, I am without a web site. I 
hope to pull some strings (so to speak) and get the U of Minn to allow me 
some space with out having to pay the extra prices. I'm going into my 
finals now, so I'll be busy till mid March perhaps. I have all my pages and 
stuff backed up..thank GOD...before they erased my site. So, if I do get 
back on with a website, it'll look similar to the ones you've all seen with 
some minor changes. 

Since I do not have a website anymore, I'll post my par files on here when 
I get home. I'm still at the U right at the moment. I have three papers to 
write in less than a week's time. UGH!! Then finals....ARGH!! Well, 'nuff 
said. Hope for the best, it just might happen.

Try Whole Earth Networks*.  My ISP, a local subsidiary called Hooked, 
provides all the usual internet doodads (Web, e-mail, FTP, IRC, 
newsgroups, gopher, etc.) plus 20 MB of Web storage for $25/mo.,
which would be about the same as the $100/quarter you're paying now.

You might consider going with a commercial ISP.  My ISP, DNACO, sells a
shell account with 20MB of space (web and otherwise) for $14.95 per
month, which adds up to $200 per year.  (Although, if you buy a whole
year at once, they discount it.)

I imagine you can find ISPs in Minneapolis (is that where you are?)
that will give you such things for similar prices.

Bud,

I would try them, but I'm finanacially unstable at the moment. PLust the U 
of Minn is very close, so I have some good connection through FTP. Plus they 
have some of the best school software around (propriatory though). But I'll 
see what I can find.

Karagen,

There are quite a few here in Minnesota....yes I live near Minneapolis. East 
Saint Paul. I check the papers often to find some good ISP's. My mouth 
waters when I see ISDN or T1-T3 connections. But get stumped when I see the 
prices...hehehehe. My page will be back sooner or later. But now...gotta 
write my paper.

Happy fractaling

Not necessarily.  P-II and PPro chips are optimized for 32-bit code, not
16-bit code.  16-bit code does not perform as well.

	I will look into inserting the altavista search engine into the
fractint documentation. I agree that a searchable database would be a
great feature for the fractint docs. It will be a few days before I can
look into it. My web world is crumbling around me at the moment. The monitor
for my PC blew up a few days ago and is in for repair and this morning the
alphaserver which runs netscape under Xwindows crashed during an upgrade.
When I get access to a browser again, I will check out the html insert that
Paul sent. 

	As for expanding the docs with other tutorials, I would be happy
to provide links from the fractint page to other worthwhile pages. I've
expanded the existing docs in the past with contributions from
other fractint users. I feel the PHC tutorial, the formula tutorial, and the
L-systems tutorial are great examples of useful extensions to the fractint
documentation. I have hosted them at spanky and done a lot of the work in
converting them to html, but I don't always have time for this. I would 
much rather just add links to other pages as long as they are maintained
in a responsible manner and the content stays on topic. My own preference
is for relatively simple organized text with graphics examples to hilight.
I tend to shy away from complex backgrounds or graphics that don't 
add any significant information. I think some peoples fractal backgrounds
are very beautiful, but many are too intense and are a distraction from
anyone concentrating on the text. I am also not a fan of advertising and
regardless of personal preference, I am prohibited by campus policy from 
adding any to any page that I host. 

	A number of people have asked me over the years, why I don't 
improve the look of the fractint documents on the web. My main reason 
is simplicity. I try to keep the pages as close to the information 
distributed in the program as I can. For every new release of fractint, 
I have to get a merged list of differences between the old and the new 
docs, and apply them to the pages. There is a significant amount of 
editing involved, as page references are meaningless, and a lot of the 
syntax used in the docs has problems in html and has to be modified. 
If I diverge from the existing format significantly, that job gets more
complicated. 

	So with all that said, I would be happy to have people contribute
links to expand the fractint documentation. I know there are several pages
out there that have fractint tutorials. I would be happy to link to those
that people here find helpful. I think the big problem with maintaining a 
distributed information system is maintaining control of content. I don't 
think we need links to 20 tutorials all covering the same topic. We should
have some method of selection and a way to distribute different topics. 
A little overlap is inevitable, but we should try to control it somehow. 
A lot of topics discussed on this list would make great tutorials. The whole
colouring algorithm thread, the anti-aliasing discussion, as well as
a basic fractint for beginners would be useful in my estimation. 
Perhaps we can come up with a voting method or a peer-review process
by the list members here to any pages that are nominated for addition
to the fractint docs.

	Feedback please!

	Cheers,
	Noel Giffin

There is, at the end of the fractint docs - at least in my version of
fractint 19.6, a synopsis of sorts titled: FRMTUTOR.TXT, An Introduction to
the FRACTINT Formula Parser, written by Bradley Beacham. This part is in
and of itself something of a shortened version of the fractint docs and is
something like fractint 101. It is similar in its approach in many respects
to Lasker's Manual of Chess (if you are a chess player you know what I am
talking about) in that it takes one from the very simplest explanations to
the more complex areas very well. Example:

6.2: "...Imagine a cicle drawn on the ground, with a little ball sitting in
the center. We'll pick a spot on the ground, somewhere within the circle,
and call that the 'test point'. Now we will start moving the ball in
discrete steps according to a set of specific rules (which we won't
describe yet) and watch the path that the ball takes."

This tutorial can very well be recommended as a beginning step.

This would be good. A compilation of color maps as Angela suggested would a
very good thing IMO.

Hmm... I'll give it a whirl :)

Untitled (First Iteration)
- --------------------
What would a triangle be
If we only could ask it?
It might just reply,
"A Sierpinski Gasket."

Untitled(Second Iteration)
- -------------------
The TwinDragon's hearty lunch
Is cow's knees a' la feet, not.
Rather, you'll be glad to know, they 
Minkowski sausage eat, hot.

Both original poems by Jason Hine.

Thanks and apologies to Oscar Wilde.

Hi Angela,

It's a mystery no more, read on...

Assuming you don't specify "recordcolors=3Dyes" then Fractint saves the n=
ame
of the color map in the par as long as you've plugged the map in and done=

nothing else. The moment you cycle that map, even one notch to the left o=
r
right, it's no longer the same as when you first loaded it so Fractint ha=
s
to record the full color code. Try it and see.

cheers, Les

Subject: (fractint) carr 3371

I spent a long time last night zooming around in this image-
It's mysterious and changes as you rotate it, with all kind of things in

there like an Indian headdress, CAT scan of the head, coral reef and...
.......(.maybe I just need a long rest).  Anyway, it draws slowly and is

just 3 different color palettes but I thought it was interesting.  It
has to be drawn in at least 1024 x 768 to work.

Subject: (fractint) Colormap bundling

	Hi all  - I've newly subscribed to this list, lurked for a little
while, and now
want to tell everyone how much I enjoy the discussions, and add a note
myself.  
	I would have kept quiet longer, but for the comment about
bundling better
maps with Fractint, something I've desired since I got into Fractint with
v17. I would
totally like to contribute a map to that effort (as would thousands of
other people,
I'm sure) So what are we to do? We need some sort of voting to be able to
chose 
one out of several similar maps. If we need a committee of colormap
experts, perhaps 
the reward for serving on this body would be the inclusion of a favorite
map. 
This might be overkill. It would be nice to do a really good job on this,
and it's a great
way for non-programmers to contribute to Fractint. At a start, we need a
volunteering
of web space from someone who's got a bunch, so that those who want to
submit can 
upload a fractal that highlights their colormap. Then we need some
mechanism 
for voting. And, some decisions need to be made, how many maps total, how
many
each of various types of colormaps, etc.  It might be good to have some
examples
of the same periodic map with different frequencies. I find it
exceedingly useful to
have several to apply, as changing this variable - I think of it as speed
or rate of the 
colormap -  has similar effects to changing the logmapping - but it
doesn't require 
recomputing. I have a few series like this I could offer for
consideration.
	I don't have the answers to all the questions of how best to
choose
the colormaps to bundle with Fractint, but I do want to participate in
the discussion.

	Looking forward to helping make a great program more beautiful,

The current implementation of big numbers in xfractint is awfully
slow, ineficient and badly made.

One could optimize that a lot and use a faster algorithm to multiply
large numbers.

If somebody is intrested in some better algorithm, contact me and I
will give him some sources. I myself unfortunatly don't have the time
to integrate them in xfractint.

May the Source be with you.
