Hi all,
I just finished writing a macro to tile boxes on a sphere and here is
one image that came out of it (it's pretty unifinished though).
Makes me think of a small planet with far too many buildings.
The second image is to show what the macro can really do if anyone
interested.

Humm... Travelling North-south would aslo be a pain in the back as you'd

Cool. Post it to P.B.T-F. I'm sure someone will find it useful.
I was actually thinking of doing a macro like that the other day, but laziness
and other things got in the way.

Well, same here. But I was able to decode them the hard way. Here they are,
the yEnc way to save space....

I posted the source code to P.T.S.F. (file is not so long) with several
examples included tha use brick but it is theoritically possible to tile
any object on a sphere (dimensions are taken from object bounding box).

I posted the images with netscape newsreader so I guess I will have to
check my options are ok. Sorry you can't see them.
The good news is that source code is in P.T.S.F. so you can render them...

Yup, same problem for me with the original post.
Your yEnc versions worked well, thanks!

Folks, Heres my "fiddle with his macro" results using text instead of
boxes.
One of my problems with Pov is my lack of remembrance with geometry math,
high-school was only 20 years ago for me...
I couldn't come up with such macros if you paid me, well then again there
the big library called internet to help...
Thanks for sharing Nico.

You're welcome. I learned so much from these newsgroups that it's quite
natural to share anything that might be useful...
Nice image by the way.
I'm still struggling with my boxes to make it looks like a big city. I
think I have to add some clouds but I do not know what method could suit
my needs since I think I need some "volumetric" clouds. Any idea ?

Hi Nico!
> "volumetric" clouds. Any idea ?
Scattering media could be a way to achieve nice realistic looking
clouds. Perhaps you could have a look at Gille's MakeCloud macro which
you can find at http://www.oyonale.com/ressources/english/sources13.htm
Another nice example is Tim Nikias' "Worldbowl":

My clouds are boring and flat, volumetric I have yet to tackle..

It did notice...
If you were trying to center (to the origin) the passed object
to your tiled_sphere macro, I believe this should of been the
formula: -Min-((Max-Min)/2)
Just -(Max-Min)/2 was only moving it closer to the origin by
half the objects size.

Yes, yes, you're right. I realized that a few minuter after having
posted the code. I have to correct it in p.t.s.f.
In fact, I'm using - Min - <(Max.x-Min.x), 0, (Max.z-Min.z)>/2 to have
the bottom of the object lying on the ground in order to avoid some
collisions.

I think this may be less confusing though (results are the same)
- Min - < (Max.x-Min.x)/2, 0, (Max.z-Min.z)/2 >

Thanks to your macro, I was able to complete an image I've been wanting to do
