What a lovely image. Pure glass, i mean class. Your marbles are definitely loose.

I'm sure small boys would love to play with your balls,
but first you've to smoothen some of them.... they are edgy

@tato: you could use sphere primitives instead of lowpoly sphere meshes.
example (gives you a perfect sphere):

Code: Select all

	<sphere>
		<center>1 0 0.3</center>
		<radius>0.3</radius>
		<material_name>mat</material_name>
	</sphere>

there is no perfect sphere

but i try it.

ok. here comes.

after 7h. i changed the camera a bit, colored floor and added some dispersive refraction. what a words

what i found is that the perfect spheres speeded up the rendering nearly 2 times. from 30k to 55-60k. hm, and gives me different refraction

hmmm.... the refraction is much stronger than before...
But I think, the pic looks better through

Very nice.
Perhaps you could put some absorption in the glass? For example it would give a green tint to the green marbles.

hmmm... But the glass for such marbles is clear, isn't it?
For some reason, I've seen some with a very weak yellowish tint...
Yellowish/Beigeish....

And also there are quite often bubbles inside...

Well..sometimes it's clear.
But either some absorption, or some imperfections in the form of bump mapped scratches etc.. on the marbles would look good.

I think, imperfections are better^^
Or a somewhat yellowish tint, like some of them have... Greenish isn't usual for marbles. Or at least, I never seen any.

Its interesting that photography tries to get clean, nice, nearly "steril" pictures and CG opposite ...

I wanted yellowish ground but i dont know what WB set for HDRI lightning.

and I am missing also apperture shape setting. to get nice out of focus hexagons or anything ...

people every time want to get things, they can't:
In Photographs, it's impossible to get a perfect shoot. So everyone tries to^^
In CG, it's quite hard to let it look real. It's partly possible, but anything will be missing any time.
A great increase in realism is, to break the perfectness.

And the floor IS yellow, just a bit underlit
