Challanged by James S., here is a quick image I threw together with many
objects generated by not so many lines of code. It took 13 minutes to render
with area_lights and focal blur.

Beautiful. It's images like this that make me spend so much time here!

pretty cool. you should use the fractal idea in the random level
generator... that's what this scene looks like. a level from a video game.

Maybe it's just me... something looks "wrong" with that focal blur...

Very nice.
Is there something misaligned though? The main 'object' that the sphere
sits on has what appears to be a small step on the top surface (just
left and in front of the right middle protrusion). Same on the left face.
I don't see it repeated in the smaller versions
Perhaps it is deliberate but I think it might look better without this.
And yes - the focal blur looks a bit strange. How about moving the
focal point and aperture to sharpen up that foreground peak and blur the
background ever so slightly.

Those are actual steps. That large surface is actualy made up of several smaller
ones, and they don't all line up.

It can be there but to small to be visible...

Nice image, I like images like this with just a bit of colour and the metal
texture is good. The sphere looks a bit elongated on the y axis is that on
purpose?

Well spotted! It took *me* a while to figure it out at first.

That's possible. The thing is that the ratio between the cubes and their
"children" are sometimes close to the golden ratio, so with the right
alignment and random factors, you get edges that almost, but not quite, line
up.

Thanks!

Yes, and it's actually a superellipsoid.

Thanks! On the other hand, is that a good thing or a bad thing? ;)

Hmm. It's a bit difficult to ensure that a randomly generated level doesn't
become impossible to solve, if it doesn't follow strict rules. I wouldn't
know how to apply a fractal-approach to it...

I felt so too, especially when the blur (aperture) was stronger. I think
it's the complexity of the scene and the measures of depths that trick the
eye, so things look like they have a different distance to the camera than
they really have (see attached image).
But I don't know what to do about it.

As Alain said, they are actual steps, just like all the other ones in the
geometry. Since it's all random, I can't directly control it, other than
trying to use a different random seed, which will completely change the
image.

That's a possibility. I think I'll try it out and see how it looks.

Fractals typically possess scale invariance, which makes it very hard to
figure out how big they are. ;-)
(Take a small rock, put it close to the camera, and watch as it becomes
a mountain peak. Brilliant stuff...)
No, I'm not sure what you can do about it either. Ho hum!

I should have said - You have defined a new variant on RSOCP:
RSOFP - Reflective Sphere On Fractal Plane.

Yeah! ... except it's not a sphere ... and it's not a plane ...

I like this. Simple, to-the-point, and draws your attention. Well done.

hi. any chance of a larger render (ie. 1920x1200, ie. my desktop ;-) or
the source for this render? i *really* like it. thanks.

If it is round and shiny then I'll accept even a superellipsoid.
And if the plane was indeed a plane it wouldn't be fractal - at least
not an interesting one.
So RSOFP it is :)

Thanks! :)
The source code is now available from here:

time to let the new AMD 4600+ have a run. i just now realised what it is
about this scene that i like: it reminds me of my Amiga 1000 and Marble
Madness. i loved and hated that game...
thanks for the source!
