nice just tried it on my ps3, fast and fairly smooth good stuff :)
no PS3 here yet, so:
is it zooming? if so, why is it declared as procedural graphics ?

hardy: yes it's zooming. Read the nfo ;)
slippy: yes I think the sourcecode is worth sharing. Once I get the toolchain bug workarounds removed and the code properly commented, I'll release the sourcecode.
and propably some signing for official/custom firmwares, too? :)
have nothing to run it on but thumb up for pioneering (:
What RRROAR said.
what sensenstahl said.
what baah said.
/me demands video.
nice
Yes, nice to see some more releases for the PS3!
Good use of the SPEs, I'd be reallly interested to see the source as I'm currently messing around a bit with PS3 coding as well.

RULEZ :)
It's beginning!
for the screenshot and for cell programming
Tried it on my ps3, it rocks!
No PS3 here, but thumb regardless.
perhaps it's better to have a video, since most of the people voting here are judging a single (and sooo common) mandelbrot screenshot because they doesn't own a jailbroken PS3...
rez: a few people have confirmed that it works. Beyond that, it's a mandelzoom, running on cell. Is that not worth a thumb? :)
yes
Thumbs up for this, proving that no, jailbreaking is not just to run pirated games, but also for legitimate use of the machine :)
zerkman !!
YES
keep it up
Um realtime Mandelbrot has been around for what...? 12 years at least.
@photon i think the good part is not the realtime mandelbrot but a good coded, full threaded homebrew release for the ps3... looks pretty though, so thumb
works smooth on my gh-3.55 :)
what psonice said.
i wish i had a ps3
video FFS
I've got a PS3.. Is there any risks/downsides to installing a fw with the package installer enabled? (i.e. will sony be able to detect this, etc).
Video please! :)
Video please! :)
Rocks!
Nice & thx for the source code :)
Here is a a video. Quality is crap, since I couldn't record the HDMI output of the PS3 (thanks to HDCP) and as it's an interactive app it would have been weird to generate images from the app. So I filmed it with my old Fuji camera. If someone can make a better video out of it, please do.
kikass. Mandelbulb next ? :)
I save my thumb for a mandelbulb
I love mandelbrot and PS3 so it rocks :-)
Btw, could you tell us a bit more about what toolchain did you use to build such PS3 demos? Any url available?

have watched the video above. ass-kicking thingy. Great work! <3
Nice!
a little thumb up for the fast gpu-mandelbrot on PS3, I hoped to see a deeper zoom in the video, but perhaps you avoid to do that because framerate drop to much ;)
leonard : I used the psl1ght SDK, on top of ooPo's ps3 toolchain.
rez: The GPU wasn't used, only the SPUs of the Cell processor. And deep zooming was prevented by the use of the single precision float format (and Cell performance sucks at double precision).

Goil! Finally someone without access to the Sony SDK is doing it natively, so even PS3 Slim owners without the "Other OS" / Linux option can watch it.
Cool! Works realy nice!
Looks great, also nice idea with the controlling.
! I hope to see a lot more for the ps3. such a cool platform for demos.
Just for fun, I just added an old 4kb "deep" Mandel Zoom I made some years ago. You can get it here:
http://www.pouet.net/prod.php?which=56614
As Zerkman say the zoom depth is limited with single precision float. I use double, wich is quite slow on CELL/SPU.

Nice Leonard, but unlike your version, the PS3 version does not seam to use the zoom trick, every frame, every pixel seams realtime calculated probably in 1920x1080, i'm not sure about the actual resolution, but it is pretty high with a very decent frame rate.
PauloFalcao: indeed on the shown video every pixel is actually calculated in 1920x1080, 128 iterations, as you can "see" in the source code.
yes Paulo, PS3 mandel is really computing 1920*1080 pixels, which is really impressive, and don'"t use "zoom" trick.
My version use a nice trick wich could be used to otimize the ps3 version, but the algortihm should be a bit harder to run on SPU with good load balancing. Basically the idea is that if you can find an area of the mandel where the perimeter is made of the same pixel, then all the enclosed area can be filled with that pixel value. This is a "huge" optimisation, but tricky to do on SPU

Where is leonards mandelzoomer (for PC I assume)?
Pouet link seems to be invalid.

leonard: your "nice trick" doesn't work with smooth colouring. Not even in the black area without precision (and quality) loss. I could use another mathematical trick to speedup the black part rendering, but it was fast enough ;)
wtf? each time i navigate to the link posted above, the address bar says http://www.pouet.net/prod.php?which=56614 but I get a different page each time!?!?!?
hooverphonique: the above link was a dupe, so admins removed it, and a removed pouet id link redirect to the "random prod" page :)
good
Just checked it yesterday on my PS3 ... it's really fast ... and nice :)
Thanks Zerkman. It's better than nothing. :)
Nice! I'll try it on the PS3 emulator I wrote for the Falcon :)
The trick given by leonard can be SEEN here:

Nice
Nice!
Mandelbulb please?
Zerkman:
Bien joué, mec. If you have time give us MORE! Appart the PLASTIC dudez!!, you are the pioneer on this field.
What are your plans?

btw is there any good windows rt fractal zoomer?
Fractals on the Cell!
Excellent use of the SPUs with async DMA! This is how to take the most out of the PS3.
Limited zooming...
Zerkman just rules !

if this prod is a fake, some info is false or the download link is broken,
do not post about it in the comments, it will get lost.
instead, click here !
any chance that you provide the sourcecode for that thing? As you can be seen as pioneers on that console it would help the community to have nice tutorials :)
