An arbitrary number of starting lines (red) are written:
#declare starting_lines =
array[4]{
array[2]{ <-1,-1,-1>, <-1,-1,1> }
array[2]{ <-1,1,-1>, <-1,1,1> }
array[2]{ <1,-1,-1>, <1,-1,1> }
array[2]{ <1,1,-1>, <1,1,1> }
}
And then it will build a webby structure between them.

Can you make the lines sag? Right now they are perfectly taut.

Just trying out the web structure again. I allowed definable distances
to govern the strand length, so there won't be many segments that are
too long or too short. For the block, I used slope and AOI patterns for
the dust texture, and spheres were placed with the trace function. Also,
some spheres were placed randomly within the web itself. I might make a
real scene using this soon.

It's OK, it might work out for some scenes.

Spiders are always welcome. They take care of the flying bugs, and if
their numbers expand intolerably, the cat takes care of /them/ :)

No, no I cannot. In a way I can make the whole structure sag, but the
segments would still be straight. See, the macro only looks at two lines
at a time. There is no real network in place, where point associations
between many lines are kept. I thought about using some kind of pointer
system, where elements are pointed at by other elements, but I haven't
found a good way to do this. Some mesh techniques involving things like
Delaunay triangulation would be the next real step, but I'm way out of
my league there.
I suppose I could give some segments a curved, sagging appearance, but
to maintain the illusion of tautness, it would have to be done very
carefully.

Excellent, ingenious idea. Makes my nose tickle just looking at it. I don't
think I've ever seen proper dust attempted like this in any cg - the medium
usually tends to pristine clean-room perfection!
Could be a bit of mileage in leaving imprints, writing your name, etc :)

Very cool! We have lots of black widow spiders in our area and their webs look
like this. The dust looks great, too. Ingenious in every detail.

Around here, it stops at the cat. We like to let him think he's the top
of the food chain (though the infrequent visits from bears and coyotes
sort of ruin that notion).

I don't know about that. A real wizard wears a funny hat (oddly
resembling a dunce cap), and knows the ways of Voronoi, whereas I only
know the basic concepts and failed high school alchemy.

"Clean me" is always a classic message ;) Doing something like that
shouldn't be too hard. It would require wrapping the AOI and slope
patterns into an image-based pattern (or vice-versus), and also using
the same image as a condition under which objects can be placed with
trace().

Yeah, they sort of do resemble the tough, springy webs spun from black
widows. That's one spider we don't tolerate. Well, except for the time I
allowed one to live in the garden. Come watering time, she would always
exit her dwelling for a drink :)

I think the best-known rendition was by Burl Ives. (From 1957, according to
Wikipedia.)
But I have heard others.

I'm not sure how she does it. All the paper I have tried won't release
the charcoal to the eraser very easily.

Yours looks pretty good, if not realistic. Needs a little fly with a
man's head yelling, "help me!!" ;)

Neither do I. She must have used lots of erasers to reach this level of
perfection :-) Her work stands in sharp contrast to the next by Damien
Hirst, have you noticed?

Are you talking about Hirst's "Controlled Substances"? I think anything
stands out in sharp contrast to that. I'm not sure how a color key could
have made it into an art exhibit...

The same thing occurred to me -- we're infested at work. Nice effect.
Voronoi would look like Voronoi and less like a spider web. A spider
which spun a perfect voronoi web would make me question my place in the
food chain.
