Obviously there are more things that can be achieved, so I go on
exploring...

Really? I don't think so. When you follow the tracing of the slices, you
can see that blurring also occurs along the z-axis. This is taken into
account in the final df3.

Yes, I noticed the slow down. One of the things I want to try is indeed
what you suggest.

Exploring ghosts.
This could be some kind of ectoplasma. Using the First def3 density
file, with an added spherical density within the same media.

Hmm, that /is/ kinda creepy.
Reminds me of a dream I had once... I dreamed that when we die, out bodies began
to enlarge slowly, and pretty soon we were big, translucent human shapes -- much
like clouds -- floating in the skies.
I guess that it would be true in one sense, because the electromagnetic energy
that our bodies produce (including the EM energy coming from our brains) expands
outward spherically (more or less). Which star systems are 36 light years away
from us, anyway? My ever-expanding "sphere" has probably reached them by now ;)
(Assuming, of course, that the universe is continuous and my EM field hasn't
encountered problems along the way, not to mention that fact that Sol and its
subjects don't stay put.)
Oh yeah, real ghosts would look different than they appear in the movies, BTW.
Real ghosts would probably show veins, organs, bones, etc. But nobody really
thinks about that, so it's all good :)

Don't know why, but I was almost sure you dreams had to be *really*
strange. ;)

Real ghosts would surely get dispersed quickly by the most gentle breeze.

Most likely that is why most of them haunt covered places only. If someone is
interested, the Wikipedia holds a comprehensive list:

Personally I like the last one most. Really good work Thomas! Will we see it
stalking Gancaloon?
Best regards,

It is indeed. Something nobody noticed yet ;-) the shape is squeezed
along the x-axis. Presently, I don't know why this is; either during the
slicing or during the df3 generation. I need to look into this.

That would be nice! It is an end I can look favourably upon :-)

Taking the idea further, our /clouds/ would seed new stars. Well, that
happens already: we are truly star dust from earlier star generations
and the remains of the solar system will probably disperse and be
incorporated into other clouds.

Hmmm... I wonder about that. Ghosts being the quintessential parts of a
being, it would only bear the outer shape of it, if at all. No need for
all the internal organs ;-)

Gancaloon is famous for its ghosts indeed.
