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.

Ah that's nice, real nice.

This is an interesting development indeed. Spiders welcome! :-)

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.
