Sorry, I forgot to mention it's an LG (KS360) :P

If all else fails, there's still the option to turn off PNG, JPEG and
TIFF support (just like is done with OpenEXR when the libs are not
there), and render e.g. to Radiance HDR.
(Though from a formal point of view I think it would be a violation of
the POV-Ray license to distribute such a custom build, so one would have
to wait until POV-Ray goes GPL.)
> The question is "would you want to?"
Why not? At least as soon as POV-Ray can do networked rendering, it
might be an interesting option to include the cell phone in the private
server farm via BT or USB. That would also allow to trim down the cell
phone version to the bare back-end.

I'm guessing the CPU itself is not the bottleneck as much as it is the
standby time from the battery. :-) People don't run chips faster than they
need to to make a battery-driven device work.
Indeed, they usually have different parts of the chip turning on and off
hundreds or thousands of times a second to save power.

I tried porting POV-Ray to the iPhone, but had troubles with C++ exceptions,
and lack of a debugger to figure out those troubles. But that was in 1.x
times, when official dev tools didn't even exist. I should try again on a
newer firmware some day...

Heh, replied too soon, saw this post too late...
I tried and failed. But it was an old firmware and an old compiler, so it
might work if I try again...

Maybe it doesn't have an FPU? Or as Darren said, the main goal is to use as
little power as possible, not as fast as possible. There are lots of
optimisations they could have made to reduce the overall power needed at the
expense of speed.

Some memory cards, especially the microSD cards, are exceedingly slow to
transfer data. They're designed to hold phone books, not images, and even
then often take a minute or two to copy your phone book off the flash card
and into battery memory when you turn the phone on.
Check the specs on the card. You might find it's only 3K/second transfer rate.

It's an ARM processor running at 600 MHz. It's much slower than a 600 MHz
Celeron.
