Hi all!
After seeing all those Menger Sponges that had
been posted while I was gone, I wanted to
have a go at recursive objects myself.
So, I went for a sphere.
Using Electrostatic-Repulsion, I calculated
30 evenly spaced points on a sphere. Then,
I begin with one sphere, and subdivide that
into 30. These get subdivided into another
30, and then another 30.
Rendering time was 5.5 hours on my
AthlonXP 2400+, with 925 Peak Memory
(so there was a lot of Disc-Swapping involved
overnight...)
Somehow, the recursive structure isn't as
cleary visible (perhaps because I've chosen
the wrong viewing perspective, the next go
with better texture will see the entire object),
but I still like the complexity of it.
Spheres and cones, all of it, summing a total
of 1.675.861 objects in scene. Lit with
one arealight, and a shadowless fill and back
light.
Comments and suggestions appreciated!
(No, I wont use Radiosity for this ;-)
Regards,
Tim

Very cool Tim. That form is unique. That's a lot of objects. It would
be cool to try it with just cylinders instead of spheres. It would look
like some sooty tumbleweed thing.

I though of using cones to actually build
a structure of spheres which can be recognized.
Using only spheres might work with a different
angle though.

Thanks! To me, it looks pretty metallic, so
eating that isn't advised (aside of alien dinner
should be handled with caution :-)

Tim

So you've been the one who always chomped
some parts off during my first tests! :-)
