Phil,

Excellent images!  You've come up with a really nice formula!

What's to forgive?  That's exactly why I post my formulas - so that
people will experiment with them , modify them and improve on them.
Nice work!

Here's another rendering method applied to the popcorn Julia

Subject: (fractint) shell to dos

Grettings,
   I never cared a hoot about dos untill 8 months ago when I got a look at
winfract.My nature seems to want to discover the best way to accomplish so
....fractint was the carrot waveing under my nose.
I'm self taught with the help of kind friends and my brother who writes code
for a
company in D.C.
    "Pre-assumed" knowledge seems a given in any field as people get so far
past the basics that ...well...." everyone must know this. "    ex: My
brothers first explination of how to start fractint in dos was something like
: start dos ...from the windows directory move to the top of your Cdrive
change directories to the one that contains fractint.exe and type fractint.
Makes total sense now...but then...
Well...I was clueless...{ whats a directory? how change? to where?}
The explination we arived at that worked { for me } was    type cd \
then.....etc etc

     Sooooo....shell to dos?   Why?  What is it? What for?
Typeing a <d> or selecting shell to dos in the main menue and hitting enter
produces a
brief { miliseconds }  blip on the screen and I'm once again at the default
start up mandel. In that blip is a black screen that says " your image is
still hung in your video
.....yada yada ....sorry ...its the best we can do. Theres no explination of
this or why shell or how to shell.... in F1 or in fractint.doc.   I have to
assume that this 'shell to dos'
thing is a normal \ basic dos phenomenon that falls into the area of " every
one knows
this" ....but.....but.....I'm once again clueless!

     Can some one explain it and assume that I haven't a clue?  It would be
greatly appreciated.
Sincerely,
Steve

From: "Iain.Stirling" <[e-mail]>
Subject: Re: (fractint) shell to dos

This confusion is understandable! I take it that you are running
FRACTINT for dos under WIN95. That would explain why the shell
command isn't working properly (perhaps). You see, the dos shell
command will run a program (called COMMAND.COM) that will provide you
with a dos prompt. Under 95 (or whatever OS you use) FRACTINT must be
having trouble finding COMMAND.COM, and hence you are returned
straight back into FRACTINT.

Shell to DOS would be used back in the good old days when people only
had DOS, and therefore you could only run one program (this is
'single-tasking'). If you were running FRACTINT, and wanted to, say,
check to see if a GIF had saved correctly by loading a graphics
program (GWS for example), you would have to quit FRACTINT - if there
was no 'shell to DOS' command. So here 'shell to DOS' allows you to
quickly do something else during a session of FRACTINT.

Hope that has helped,

Iain G. Stirling

comment {
Here is a formula that applies my FlexBall rendering to the
Popcorn Julia equations.  Seems like an unlikely combination,
doesn't it?  But wait till you see the images - they really
surprised me.

My thanks to Kathy who got me to thinking about the popcorn
formula.

Every application I use can import the EPS version of
PostScript just fine.

FYI, I think I still have around some sample PS files
which are Postscript programs (unlike WMF and DWF,
Postscript is a full-blown language) which generate
lsystem style designs - the one I'm thinking of generates
a fern leaf.

Hmmm, now I suppose I'll have to dust off my Postscript
programming skills and see about porting Fractint to
Postscript ... <G>

All I can tell is that far more programs I've used read
EPS than they read DXF. And the conversion generally
gives better results. But my experience with DXF is so
old ...

This is indeed way off topic, unless someone feels like
porting Fractint to AutoCAD's AutoLISP? Would that
make doing 3D fractals easier??? <G> Or maybe whatever
they use in display lists???

Hi, Thanks for doing pc_popcorn_jul and popcorn_balls.
I especially liked popballs2.  It's funny because the
popcorn formula tends to break up and soften the
edges, and the edges in the 3D-stalks and other
methods are very discrete.

Your dismay is understandable but inevitable- think of it as a rite
of passage. It is easy to find fault with programmers and to think
that their work should be less obtuse but consider-
if someone asks you for directions to your home, should you be
expected to teach them how to drive their automobile first?

At any rate, shell to dos is useful in the dos world because it is
not easy to switch back and forth between different programs. Usually,
you have to quit the first program, run the second, quit it and then
return to the first. Then you have to get back to the place you were
doing whatever you were doing! If your program supports shell to dos,
it allows you to temporarily exit the program without actually quitting
it. You can then run another program and, when you exit the second, can
easily return to the first w/o having to reload it. In the case of
Fractint, this would be useful to let you use an editor to work
on a formula file w/o having to shut down Fractint.

Lest you think my first paragraph a personal criticism, let me say
that as an old hand I am quite familiar with computer arcania. Still,
I really prefer to work in Windows because things are usually so
much easier when dealing with multiple programs :)

Subject: (fractint) 3 Pars

Still shuffling through this unorganized mass or material; here are another
3 pars as I have been tinkering around:

This next one came from "Rose"; I forgot who posted it although I am sure I
have still have it around here somewhere:

This one I kind of liked:

Back up my hard drive?
How do I put it in reverse?
