Anfy Mandel 2.0 - Copyright (C) by Fabio Ciucci 1996/97


This applet can generate and animate a realtime Mandelbrot fractal.
Remember, are needed both mandel.class and Lware.class.
You must upload these 2 .class files and insert the tag on your
html document to add this applet to your page.
This applet is fully parametrized, so you can generate all kinds of
Mandelbrot fractals you want.
Here an example of what you have to write in the html (the things after
the ; are comments with min-max values accepted):


; Name, Width, Height
; resolution (1-8)
; X start
; Y start
; X min
; X max
; Y min
; Y max
; Palette number (1-27)
; Memory deallocation delay
; Task priority (1..10)
Your browser doesn't suppor Java. ; Msg in no java browsers
; End of classtag


NOTE: Don't place "; comments" on final HTML!!!

Copy and paste in your html document this cleared and correct tag:













Sorry, your browser doesn't suppor Java.

Here detailed instructions about how to change parameters:


The size of the applet is determined by width and height tags.

The res parameter determine the resolution: with res=1 pixels are small,
but effect is slow, with res=8 pixels are too great but effect fast.
I think the best choices are 2-4.

About parameters for fractal generation, I don't placed limits to values,
that can be positive or negative, place values at your own risk.
here what does the values, that can be positive or negative:

XMin: + scroll right, - scroll left
XMax: + less width X, - enlarge width X
YMin: + more height Y, - less height Y
YMax: + scroll down, - scroll up

Aniway this is not 100% correct. You are free to experiment with the
mistery of numbers.

Are available 27 different palettes, just select the one you prefer for
your web page.

Compatibility parameters:


The "memdelay" parameter is useful only to run the applets without problems
on some bugged versions of Netscape 3, that don't deallocate correctly
the memory allocated, resulting in filling all the memory after a minute
the applet is running. This can cause also a system crash in some cases.
Last versions of browsers have fixed this problem, but if you want to run
the applets on old bugged browsers too, set "memdelay" to low values, like
"10" or "16", for example.
But this will slow down a lot the applet speed, so you have to choose
between speed (memdelay set to 1000 or higher) or slow compatibility with
old browsers (memdelay set to 20 or lower).

The "priority" parameter is useful mainly when you are running more than
one applet in same page, and one slows down or hangs.
If this applet run too slow or hangs because other one steal all the CPU
power, try increasing the priority.
Otherwise, if this applet runs well and others slows down, decrease the
priority. Consider the min priority is 1, normal priority is 5, and the
max priority is 10. Usually a priority of 3 is ok for single applets.

You can use freely this applet to enhance your web pages. But since I am
the author of the applet, I placed a secret window that will appear if the
applet is clicked with mouse: it is external to the web browser, so it will
not hit the design of your beautyful html page. This small window will
simply show my name and ask for a link to my java applets page.. the user
can connect to it or cancel, or hide the window and connect after visiting
all your pages. I hope this credit part is not a problem for you...
In any case, if link is accepted a new browser window will appear and your
page will remain on the original window, so you will not lost the visitor.
Consider you will use an effect programmed by me, without pay, for FREE!
