Test mails are not a good idea and are not welcome in *any* normal
newsgroup - if you try it, prepare to be flamed!

There are a number of 'test' newsgroups specifically for this
purpose, and some at least will generate an automatic reponse to the
sender showing exactly how your message appeared to the group -
useful confidence booster.

For *this* newsgroup, you might get away with a test if you attached
an interesting par or frm!

Subject: (fractint) MISC: Subject

The topic of this thread according to my non-sorting e-mailer is:

(fractint) MISC: Subject line protocol

However, when is views the list of unopened mail, it gives only the first=
 24
characters for each mail item.  Thus I only saw (before I opened it):

(fractint) MISC: Subject

Thus I would only see the first 7 characters of a meaningful title in thi=

context.

If I reply to a "PAR" message and forget to change "PAR" to something els=

then I would be misleading others only looking for pars - I think this wi=

be a major problem that will happen frequently.  It's so easy to hit <r> =

No. The original was first information: in Win95 Control Panel/etc. and
what were the display (monitor) settings for infor re: resolution. In Win
3.1: Program Manager etc. as above, but do _not_ change settings at this
time. (If tempted to do so..., which is not what Gideon is suggesting)
Simply what are the current settings? I would suspect 640 x 480.
Next will be info on SSTools.ini what is in there at this time? (All of
this may have been covered and I may simply have overlooked it...)

What I can easily do is to leave the body of each message within the par
compilation.

The extra information will be transparent when running Fractint so it won't
affect the way the par compilation works. You won't be able to view the messages
when running the pars - but you will be able to see what goes with what if you
open the file with a text editor.

The only negative effect of including the messages is an increase in the size of
the file (approx. 40% larger).

I've uploaded a temporary version of the May '98 collection, with the messages
in the par file, to my usual page at:

http://ourworld.compuserve.com/homepages/Les_StClair/

I would appreciate if regular users of my compilation could take a look and say
which option they prefer.
Let me know by private e-mail to avoid undue traffic on the list.
I will organise the final compilation according to the majority view.

cheers, Les

Subject: RE: (fractint) Spirals Formula

Pete,

>Wow, that's really cool... But tell me, how does it (the stalks
>method) work?  (That is, how can I apply it to my own formulas?)

The first part of your question (how does the stalks method work)
is answered in something I posted to the list some time ago
explaining orbit trap/coloring methods in general and the stalks
method in particular.  I'll email you (and anyone else who wants
it) a copy of that posting.  I'll assume that some of the other
people on the list might be interested in how the Spir2_Trunc
formula implements the stalks method and what lines need to
be changed to apply the method to other equations.  I've listed
the formula below with the lines numbered for reference.  The
discussion follows the listing.

Spir2_Trunc {; Copyright (c) Paul W. Carlson, 1998
    ;
    ;   p1       = Julia set coordinates
    ;   real(p2) = a factor controlling the width of stalks
    ;   imag(p2) = max. |w| for stalks (truncation value)
    ;   real(p3) = number of color ranges
    ;   imag(p3) = number of colors in a range
    ;
1   w = pixel
2   c = p1
3   z = bailout = iter = range_num = 0
4   stalk_width = real(p2)
5   max_wm = imag(p2)
6   num_ranges = real(p3)
7   colors_in_range = imag(p3)
8   index_factor = (colors_in_range - 1) / stalk_width
9   :
10  w = w * w - c, wr = real(w), awr = abs(wr)
11  w = w - wr + awr
12  awr = abs(real(w)), awi = abs(imag(w))
13  IF (awr <= awi)
14      dist = awr
15  ELSE
16      dist = awi
17  ENDIF
18  ;
19  IF (dist < stalk_width && |w| < max_wm && iter > 1)
20      z = index_factor * dist + range_num * colors_in_range + 1
21      bailout = 1
22  ENDIF
23  range_num = range_num + 1
24  IF (range_num == num_ranges)
25      range_num = 0
26  ENDIF
27  iter = iter + 1
28  z = z - iter
29  bailout == 0  && |w| < 4
30  }

Lines 1-9 are the initialization part of the formula.  I should
probably explain line 5.  The truncated stalks method differs
from the the stalks method in that the length of the stalks is
limited by the variable "max_wm" which, in effect, makes the
orbit trap a cross within a circle.

Lines 10-11 are the equations being iterated.  You can substitute
your own equation(s) in place of these lines, using the variable
"w" in place of the usual "z".

Lines 12-17 assign to the variable "dist" the distance from the
orbit point to either the real or imaginary axis, whichever is
smaller.

Line 19 tests if the orbit point falls within the cross
"dist < stalk_width" within the circle "|w| < max_wm".  I don't
allow bailout on the first couple of iterations "iter > 1"
to allow the orbit to settle down a little.  If these three
conditions are true, the bailout flag is set.

Line 20 uses the value of "dist" to set the value of "z" to a
number which is the index into the colormap.  The value of
"index_factor * dist" will always be in the range of zero to
"colors_in_range - 1."  This is the index into one of the color
ranges.  Which color range is determined by the expression
"range_num * colors_in_range."

Lines 23-26 sets the value of "range_num" to the next number
in the sequence 0,1,2,3,etc. up to the value of "num_ranges."
When "num_ranges" is reached, zero is used instead of the
value of "num_ranges" and the sequence repeats.

Line 27 increments the iteration counter.

Line 28 subtracts the iteration counter from the value of "z."
This is necessary because setting "outside=summ" adds the
number of iterations to "z."

Line 29 tests for bailout.  In addition to checking if the
orbit point was trapped, "bailout == 0," this particular formula
also checks if the orbit point has escaped a circle of radius
two "|w| < 4."

That's about it.  Let me know if you found this explanation
useful and how I might improve on it.

Paul Carlson

Subject: Re: (fractint)newbe needs video mode

Hi davides and Gedeon!
Thanks for the info. I found the spot.  The setting is 800x600.  I don't =
find a file called SSTools.ini in my Fractint files.  Isn't that a file =
you have to generate yourself?  If so, I haven't generated one, because =
I haven't found a video mode I want to use all the time.
By the way, I did find that some of the higher resolution modes (though =
still not 800x600) that only have 16 colors do work with my computer, but=
 I'd rather get higher resolution and keep at least 256 colors.
One of the 800x600 modes did seem to be trying to function on my computer=
 -- it was running, but all that was displaying was a black screen that =
was flickering rapidly.
Anyway, any more ideas?
Thanks for your help.
Colleen

Hi RJ
I have a floppy disk with the most recent drivers from the manufacturer's=
 home page.  I'm going to have my hubbie look over the files and see if =
there's a DOS driver in there that might make a difference.  But the mode=
s don't work in Windows either.  There are a couple of other drivers or =
programs that came with the video card that aren't installed on the compu=
ter that I'm going to ask him to install and see if that helps.
Thanks!

Hi Kerry
I was reviewing and deleting messages, and realized that I couldn't find =
the response I wrote to you amongst all the files in my in-box.  I don't =
know if I had just already deleted it or if I sent it to a different addr=
ess at your request, or what.  I know the list seemed to be acting kind =
of weird this past weekend.  So, anyway, I thought I'd send it again, so =
you wouldn't think I had ignored your message.  I hope that's OK. So here=
 it is:

Thanks for your response.  I've tried all of the modes in the config file=

already.  A few of them worked, but they are ones with fairly low
resolution or few colors.  The specs for my adapter and monitor suggest =

I should be able to get better resolution.
I'm not sure how you all attach the note you are responding to to your =

message.  I'm going to try to attach my first note to this response to =
you.
I hope it works!
Thanks again.
Colleen

Wow, am I glad to find you guys.  I'm fairly new to computers, and very =

new to  Fractint, and I'm having trouble figuring out how to configure =

Fractint to maximize my computer's potential.  And I need to maximize it =

because I have a 486 and Windows 3.1.  Anyway, I'm getting what
seems to me to be rather low resolution on my fractals, and I've been
trying to add the specs of my video driver to the config file, in hopes =

that that might improve things, but so far all I get on the screen when =
I
do that is scrambled pixels.  Can anyone help?

I have a Cardex W32 Local Bus Window Accelerator VGA
(ET4000/W32- VESA Local Bus)
(I'm typing all of this directly from the pages of the User's Manual,
because I have no idea which parts of this information may be relevant)
In "Features" my manual lists the following:
Tseng Labs ET4000/W32 VGA Chip
Register level compatibility with the IBM VGA, EGA, CGA and MDA
Extended graphics resolution modes providing 640x480, 800x600,
1024x768 and 1280x1024 High Resolution when used with
multi-frequency analog monitors, and similar maximum resolutions with
fixed-frequency analog monitors such as the IBM 85XX series.
Support 80386/80486 VESA LOCAL BUS Operation
Support maximum 72HZ Refresh Rate in modes 640.480, 800x600,
and High Resolution (VESA Standard).
VL-BUS Version 0.8~1.x
HiColor (15,16 bit/pixel) graphics mode producing 640x480, 800x600
and 1024x768 resolution with 32,768 or 65,535 simultaneously display
colors.
True Color 24 bit/pixel graphics mode producing 640x480 resolution
with 16.7M simultaneously display colors.
Graphics Accelerator provides hardware drawing assist functions, such
as bit block transfer (BitBlt), patterned lines and circles.
1 M bytes video memory standard
Supports 64x64x2 sprite for use as hardware cursor.
Extended text modes providing 132x25, 132x28, 132x44, 132x60,
100x40, and 80x60 resolutions that let your microcomputer, using
popular emulatorand micro/mainframe link products, emulate the
display characteristics of widely used terminals such as the DEC VT100 =

line and the IBM 3278 MOD 5.
Drivers for running extended text modes in Lotus 1-2-3 and Symphony;
and extended graphics mode drivers for Autodesk AutoCAD, Digital
Research GEM, Microsoft Windows, WordPerfect, Ventura Publisher
and OS/2 Presentation Manager.

My monitor is a CTX CPS-1760/LR
The user's manual says it is a:
Super multi-frequency color monitor with microprocessor based
intelligence and multi-frequency scanning capability
It automatically scans all horizontal frequencies between 30KHz and

65KHz, and all vertical frequencies between 50Hz and 90Hz
It has maximum horizontal resolution of 1280 dots and a maximum
vertical resolution of 1024 lines with non-interlaced scanning

So, if anyone can suggest how to write the appropriate line in the
config file, I'd really appreciate it.

Thanks!!!!

You think you've got problems? Next week I will be getting my new
computer delivered--a Compaq Presario 4880 (PentiumII/400) to go along
with the new monitor that was delivered several weeks ago--a Viewsonic
17" jobber with a max. res. of 1600x1200. Then I'll be the one to have
the joy of making all my old software, including Fractint, work without
having fits and starts. But, just think, I won't have to design fractal
art at the *low* resolution of 1024 x 758 any more. 8-)

Paul, I too would like more information on how the
stalks method works.  I haven't been a member of
the group for long and don't think I saw your posting
regarding this.
