A frequently asked question.  There was an unauthorized GIF digitiation
floating about, I believe a scanned-in image of the poster "Earth from Space".

Yesterday's NYT ran a story in the business section about this dataset.
Some museum on the east coast simulated an orbiting satellite using the
original 37 million pixel dataset.  That way you can view a continuous
equatorial swath of the data at full resolution in a three minute film loop.
The film loop is divided into nine fullsize 24-bit graphics screens and
required some sophisticated CD-ROM layout to play it back.
The nine TV monitors are set in the floor, so it feels like you are looking
down from the space shuttle window.

The same article said a 600 megapixel version of this dataset was being
prepared by the Geosphere Project, which according to my calculations is
1.5 minute of degree on a side, or approximately 1.5 mile per pixel.
You can start seeing cultural features (cities, farms) at this resolution.

You are assuming, of course, that this is a stable problem.  It is
not clear to me that the points will ever degenerate into a single
configuration.  Can you guarantee that they won't constantly
be moving around and orbiting each other, etc ????

Not to knock your solution, I just thought the counterpoint was
interesting.  This solution is actially just another way of 
stating the "point-charge" method mentioned a couple of days ago.

Seems to me you could use radiosity techniques to render any scene you

What do you mean by "anatomical objects"?   Body parts?

My reference for this is a blurb for a product called "Fast Eddie", on page

Hi:

I am trying to load 16 color gif and ppm files on a PC that has

using the SetRGBPalette procedure.  It appears that when I try to load my
images using the PutPixel procedure, the program reverts to the 16 
predefined colors.

I quess my question is, if I want to define a new set of 16 colors, each based
on a set of red, green, and blue values, how do I make the program use
these colors instead of a rearrangment of the orginal 16 predefined colors.

Also, does anyone know much about the Bitmap type used by the
Get and Put image procedures?

Any help would be **GREATLY** appreciated since I know very little
about PC graphics.

Please either post a response or just E-mail to me.

Okay, I can't be the only one who wants to know what papers made it into

So if your paper was accepted, send me a note with the authors and title,
and a short description if you want.  I will post a list of replies that
I get.

PLEASE DO NOT SEND ME MAIL IF YOU ARE NOT A PAPER AUTHOR.  ABOVE ALL, DO
NOT ASK ME TO SEND YOU THE LIST.  ABSOLUTELY NO "ME, TOO" MESSAGES, PLEASE!
I WILL POST THE LIST AFTER I GET RESPONSES.
