Created this image recently, involving a shape I constructed a couple years
ago screwing around in AutoCAD. I was able to recreate it in POVRay...just
felt like posting. Bonus points to any who can tell how I made it (what
it's made from, etc.). I can post a different version without all the
mirrored surfaces if it would help.
6 finite objects: the walls and the central "thingy".
1 finite object: the base plane.
3 light sources: a shaped light, a spot light, and a random point light.
I'm just getting used to this software...take pity.

It's four spheres arranged in a tetrahedron and differenced from a central
sphere.

Nope...sorry. Notice, it's somewhat cubical: that would imply six spheres,
but the main element isn't spheres, either. Note the hole in the middle
where everything comes together, and note also that the curvature on each
side is opposite that of a sphere. Here's one made of wood for better
examination. (About 5 minutes for rendering at 1680X1050, my desktop
size). And, there are no difference functions involved (though I am trying
to hollow it out so I can fill it partway with water; any suggestions on
how to do so?).

Well, that would depend a little on how you made it ;-)
Is it a mesh or an isosurface?

Sorry, Mike...
I used no external modeling program for this...it's all made in POVray.
There are some Boolean constructions involved, but that's as far as I'll go
for now.

Sorry about my screwup...here it is a little less reflective.

The wall behind the Thingy = 1
The walls left and right = 2
The walls behind the camera = 1
The ceiling = 1
--
summary = 5
Remains 1 Object for the Thingy, sorry but thats only possible with a
mesh or other mathematic solutions (dunno the names atm)

Do you mean *in*finite?

In this point I have to trust you :-)

I was used a very little to some older Versions (pre 3) but I made a
very long pause, I have to beginn from zero :-(
I hope we can solve this puzzle earlier or later (is there some phrase

I might be mistaken, but I don't think a plane counts as a finite object...

In the OP there is listed only a baseplane as 1 of 1 finite Objects, but
i suposed he meant infinite in this case, and baseplane is floor for me,
but even if it is the ceiling or any other wall, than you can exchange
it vice versa with the corresponding item in my above list...
It simply makes no differnce.

I guess it's not really clear from the top post in the thread - I am
pretty sure, though, that planes within POV aren't counted as finite
objects, and assume that the walls are planes as well.
