Hello,

This is my latest desktop wallpaper attempt. Is are 110592 cubes, placed my
an algoritm. This image has an "recursion-level"of 3, and i am currently
rendering one with level 4, which has 48 times as much cubes.

a large .jpg version [1600x1200] of both images will be available at

home.student.utwente.nl/j.w.a.vaandrager/background_L3g.jpg

change the L3g to L4g to view the "level-4" image when it's done.

Comments and critisism is welcome as usual.

Greetings,

JWV

The level-4 render was to much for my laptop :-(. It used 2GB of memory
while parsing, and it wasn't finished jet.

I will post the source in p.b.sf if someone wants to give it a try on a
machine with a LOT of memory  :-).

Greetings JWV

That looks cool!  I might give it a try if you post the source.

Post a reply to this message

the source has been posted. You can change the recusion level by changing :
#while(cnt<4)
in line 19, into cnt<????

I is set to 4, which means recursion level 4, which was to much for my
laptop. So you might give it a try with level 3 first.

Greets,

JWV

i'm peeved / tee'd off

dual 2.8 xeon, 2gb ram, explicitly added 2gb of swap space above its 
norm of 1gb and still ran out of space with recursion level of 4

anyone got a machine that can render it ?

Thanks for trying it! The level 4 scene should have about 48^4=5.308.416
cubes. I am not sure how much memory is used for this amount, but it apears
to be quite a lot.

Greetings,

JWV

I've got 1 gig RAM and 6 gig of page file.  I was watching the memory usage
and it claimed out of memory at 2gig.  I seem to recall hearing something
about a 2gig maximum of memory for an application regardless of the total
amount available (Windows).  Does anyone else know something about that?

having read replies so far, is there a question of OS lurking ?

if so, linux originally libranet 2.8.1, now tracking sid istr, kernel 2.6.4

Win32 applications are limited to using approximately 2GB of memory. "Out 
of memory" in this case really means "out of address space". The total 
address space is 4GB, but applications are only allowed to use half of it. 
Applications that work with data sets larger than that must take special 
measures in order to do so.

	It should be possible to decrease the amount of memory required
(divide it by 4). At the first iteration, since blok is a simple cube,
balk is equivalent to a box { <0, 0, 0>, <5, 1, 1> } although it is
done with 4 boxes. Even with that I don't have enough RAM to give it a
try from what you're all saying ("only" 512M) but some of you might
want to try it.

	Of course, this is only true so long as f is set to 1, with higher
values the results won't look the same...
