First day of school today. In biology, we had to do a metric measurement
worksheet, and some of the problems involved a rubber stopper shaped
like a clipped cone. The top diameter was 2.2 cm, the bottom diameter
was 2.7 cm, and the non-lateral height was 2.5 cm. One question asked
the volume. Another question asked how many could fit in a box the size
of the biology book, which is 20.65 x 25.5 x 4.5 cm. The instructor
simply divided volume and got 200-some. But this raises an interesting
question: exactly how many clipped cones can fit into a box? I got 110,
my method was a hexagonally-tiled row along the 20.65 cm axis. By having
the upper row flipped from the bottom row, I figured 11 could fit
together without exceeding the height of the book (6 on bottom, 5 on
top). Then 10 of these rows could fit in the 25.5 cm length. That gives
110, but can anybody do more?
For a large enough box, I think the most efficient way is to tile them
in hexagonal layers like cylinders, but have every other row
"upsode-down". Then stack layer upon layer until the box is full. The
top or bottom of each layer would be like so:[Image]

Hi, Larry.
May I suggest that images (binary attachments) be posted in p.b.i.
(povray.binaries.images) for the sake of organization? Post your discussion
messages in the appropriate group (povray.general, povray.unix, etc.) and
mention that the pertinent image may be found in p.b.i. Similarly, when
posting the image in p.b.i., use a line of text to indicate which group your
discussion posts may be found. It also helps to make the subject line of
both the posted image and the posted text message similar in wording.
Keeping the binaries in their appropriate groups makes it much easier for
another newsgroup participant to find your image, say two months from now.
They may not recall which group the discussion took place in but they'll
know exactly where to look for the image with a specific subject line.
Thanks for your participation in news.povray.org.

Personally I like it more when people mention an URL to the image instead
of posting it to p.b.i. It's much easier to just copy the URL to netscape
(or just clicking the url in some newsreaders) than going to another
newsgroup, searching the post in question and coming back here.

The only limitation with this method is if in some future time someone else
wishes to see the referenced image the file could well have been removed
from a web site while it will still be available here on the server. I often
reference back to past messages dating as far back as the beginning of
this server. If refereneced material was unavailable the content of some
messages would be worthless. I will also agree though there are case where
is is appropriate top provide a link to some temporary data of no importance
but in this case it is an important part of the data in the message and
should not be time limited.

What about us 33.6 analog line offline readers?

FWIW, I agree that the figure as an important part of the message ought to
be inline.
Especially for line drawing like this, which should be a =lot= smaller than
the actual JPEG. A bilevel PNG would have been much smaller, followed by
2-color GIF.

I think it's funny that the format of his posting got all the attention,
rather than the -subject-. So how many corks do fit in the box?
