Does it make use of Altivec?

No Altivec yet, but we are working on it

Tried it twice on my µA1 with OS4.
As soon as I click the left mouse button on
the palette window my WorkBench colors get
messed up and I get a visit from the
Grim Reaper. Does it work on your A1??

This is the non working and non optimized code of Altivec function (ont he top there's the non altivec commented code):

/*
* Mandeln_altivec_V3.c

WORD Exp;
LDouble zr,zi,zr2,zi2;
const LDouble maxdist = 4.0;

zr = Cre;
zi = Cim;

while (--Iterazioni) {
for (Exp = Power; Exp != -1; Exp--) {
zi2 = zi * zi;
zi *= zr;
zr2 = zr * zr;
zr = zr2 - zi2;
zi += zi;
}

if ((zr2 + zi2) > maxdist) return Iterazioni;

zi += Cim;
zr += Cre;
}
return 0;

*/

#include
#include "FlashMandel.h"

#ifdef __ALTIVEC__
#include

WORD MandelnAltivec(ULONG Iterazioni, ULONG Power, LDouble Cre, LDouble Cim)
{
WORD Exp;
vector float maxdist = (vector float) {4};
vector float zero = (vector float) {0};
vector unsigned int cmp = (vector unsigned int) {0};
vector bool int exit;
vector float vCre = (vector float) {(float) Cre};
vector float vCim = (vector float) {(float) Cim};
vector float zr = vCre;
vector float zi = vCim;
vector float t, zi2, zr2;

while (--Iterazioni)
{
for (Exp = Power; Exp != -1; Exp--)
{
zi2 = vec_madd(zi, zi, zero);
zi = vec_madd(zi, zr, zero);
zr2 = vec_madd(zr, zr, zero);
zr = vec_sub(zr2, zi2);
zi = vec_add(zi, zi);
}

t = vec_add(zi2, zr2);
exit = vec_and(vec_cmpgt(t, maxdist), (vector bool int) {TRUE});

if (vec_all_eq(exit, cmp)) return Iterazioni;

zi = vec_add(zi, vCim);
zr = vec_add(zr, vCre);
}

return 0;
}
#endif /* __ALTIVEC__ */

If someone knows how to implement it we all can have one of the first programs supporting Altivec
For now using this code Edgar on his A1-XE@933 get only a black screen

Bye,
Dino Papararo
We're also looking for some good Arexx coders for build a strong benchmark test for cpu/fpu/altivec (when imlemented) and a nice amination builder.
Sincerely there're already these Arexx routines but we want someting better, I'm sure the Arexx port and Arexx commands in FlashMandel are underestimated

I tried it on my AmigaOne-XE G4 and I have no problems.
Can you please generate a crashlog and send it to me?
You can create it in the GrimReaper-window. Click on the
crashlog-tab, activate "Include stack trace", "include
system information" and "include list of system libs/devs"
and then click on "Write Crash Log".
The crashlog-file will be located in the ram-disk.

Because I have no problems on my system, there is no other
way to solve this.

I got it running on a µA1 no problem, but the installer crashed before adding the ASSIGN to user-startup, and it doesn't seem to want to use the tooltypes in the icon. I've got a 1024*768 screen and I'd like to use it. Also, 256 colours is far too low.

Also, that noise it makes when you run it is absolutely infuriating. Please stop it.

Tried it on Peggy.. it reports my cpu as 68k heh

geez... just read about program name FlashMandel for Amiga, happily jumped here to read more about it and found it is NOT a Flash player... but another fractal renderer...
I guess Amiga will never have normal flash player with sound :( :( :(

I'm sorry but there isn't still a MorphOS version, so your PowerPC will not be used
The program is open source so if someone is interested can easily port it

256 colors are used due the particular calc function choosen, the Divide et Impera formula loose all its efficiency with Hicolor or Truecolor screens.
Belive in me if I say 256 color if well used can be enough for most cases, however the truecolor mode is already planned but now there're other priorities (i.e. enable Altivec support and develop some AREXX programs)

The crash seems to be a installer-problem.
We have no problems with the tooltypes here. How did you setup the tooltypes?
Please notice, that you might have an other Screenmode-ID on your system!!!

Just delete the startup-script (FLASHMANDEL:ARexx/startup.rexx)

He he, sorry for this

I know, that Alexandre Balaban is working on a new version of swfplayer - hopefully with sound.

@Fl@sh
Here it works great, played with it for some times already.
