I was trying to emulate those super bounce balls. Placement was actually
quite easy. I placed them on an evenly spaced grid, where each "cell" has a
75% chance of containing a ball (using rand() ). Then I moved each ball a
random amount in the x and z directions, the maximum any ball could move was
half the grid spacing, that way, it would look very random, but no balls
would touch each other.

Yep, good old camera distortion. Ugh. Thanks for the compliment. I
appreciate it.

I tried something similar with my grasspatch macro. I didn't try the "75% chance
of having a ball" idea, tho. I found for really large number of placements,
there is little visible difference between the two methods (simply finding
random ponits within the boundary was the second method) and I think the second
method parsed faster...

But it looks natural and good, and that's the important thing, isn't it?

Man, you sure have balls!

Oh, and you might have a lot of guts to post here but please don't.

Sphere sweeps? Or isosurfaces? :-)

If you were going for the chinsy printed metal look, excellent job! How
were they placed?

I just read the replies. They do look like they could be bouncy balls. But
you have to admit they also look a lot lot cheap metal thing. Perhaps
hollow and the seam is maybe really a crack and it's hinged and there's a
"prize" inside.
And I saw the placement method...

I serpose they could look like cheap metal ... maybe I should've toned down
the grainy look a bit. But maybe you are right, maybe there really are
prizes inside! I'll have to render one opened up to find out ... :)
