Full  functional  program  for  rendering  Mandelbrot  &  Julia  fractals  with
different  exponents.  After more than 20 years developed and tested again on a
real Amiga: Pegasos II G4()1GHz 2GB Ram - Radeon 9250 -  AmigaOS4.1fe  :-)  From
version  2.1  FlashMandelNG  runs partially also under MorphOS & OS4EMU and use
handmade assembler routines for  max  speed.  Uses  Arexx  port,  Localization,
Arbitrary precision math and don't need any installer, just click 'n run! C and
Asm sources are also included, you can recompile  it  just  typing  MAKE!  It's
faaast  even  on  emulated Amigas and can render even with direct memory access
(TURBO OPTION) ..under WinUAE it's faster than many others x86  native  fractal
programs  ;-)  Saved  pictures  can  be  reloaded  and  further explored at all
supported screen's resolutions. It's really cool and totally free ;-)

Altivec code was developed and tested under  Powermac  G5  Quad  hardware  with
MacOSX  Leopard  10.5.8 OS and XCode 3 IDE && Ubuntu Mate 16.04 LinuxPPC OS and
CodeBlocks IDE Now I can test it on my Pegasos II  ;-)  Many  many  thanks  and
greetings  to  my  friend  Edgar Schwan, FlashMandel CoDeveloper, for his great
efforts in Localization, Arexx and Reaction integration. ***  Reaction  support
does  not  work  at moment due incompatibility between Reactor generated object
file and Os4, so for now it defaults to system gadgets.

In archive we have two binaries:

1) FlashMandelNG_OS4 -> critical routines are written in handmade assembler for
max speed on powerpc cpus 2) FlashMandelNG_OS4_altivec -> critical routines are
written in C with Altivec directives

I'd like to add another binary for Tabor ans its SPE unit, for now I could  not
with it due GCC v8 incompatibilities with SPE code; ..maybe in the next release
we got it!

..so what version is the faster one?  On  a  G4  Altivec  is  faster  but  less
accurate  due  float  calculations vs FPU doubles, so for deep zoom you need to
switch sooner to much slower high precision math.

FlashMandelNG_OS4 is Giftware, If you like it please sent me nice goodies  ..An
email or common postcard is ok too!

New in v2.3: Old heavy bug fixed - if Flashmandel didn't found a locale  catalog
crashed at startup Other fixes and little improvements applied

New in v2.2: Now finally with a real Amiga and sadly in Covid-19 era in  Italy,
I  had  a  lot cpu power and a lot of time to test and fully bugfix and cleanup
nearly all the code. Lowered resolution of all pictures to 1280x720  to  reduce
archive size, old pictures are incompatible to this new version. Added some new
palettes and changed  default  one.  Reviewed  some  Arexx  scripts.  Refreshed
english docs.

New in v2.1: Partial MorphOS compatibility via OS4EMU - Load  and  save  didn't
work  Reworked  and  eliminated  all  pre  AGA  stuff.  Now we have 3 different
binaries, normal GCC code, Altivec code and New PowerPC handmade  asm  version.
Added  DUTCH  catalog  language -thanks to Bennymee for translation Minor fixes
and changes.

New  in  v2.0:  (Re)Enabled  AREXX  support  (Please   download   and   install
AWNP_2-54.lha archive from Aminet to let it run) Fixed tooltypes

To Do: AmigaOne Tabor A1222 specific SPE version Add 24 bit palettes and screen
modes.  Add  3D  rendering Use hardware fpu until underflow/overflow limits are
reached amd then switch automatically in multiprecion Improve  AREXX  Benchmark
Mode  script  to  test  speeds of different Amiga platforms Update the very old
documentation - Amigaguide
