Because my employer has sent me travelling a lot lately,
I haven't had much time for rendering the past weeks. =(
But today I found some time to try out an idea I have.
I have made a macro in plain POV (of coarse :) that makes
blobs that seems to repel each other; thus "Antiblobs"
The first image contains 72 such blobs and the second
image contains 8.
Please comment !

Ehh ...Sorry ...
A little mistake of mine here: It contains 92 such blobs.

Very impressive Tor!
I would be interested to hear what you think insofar as practical uses for
this macro. Might be interesting to see if you could use it to simulate
deformations in the collision of objects, or other neat scientific stuff
like that.

The second picture reminds me of dividing cells...

very nice.
code maybe??

These are great! In that second picture I find it hard to beleive that there
are only 8 components to the blob... sure it can be used for a bucky ball, but
also a really really big bug eye...
Please share the code on this one, I'd love to see it.

now that I think about it, if you could animate this, like a dividing
cells or something..... maybe start with one, then it grows and grows
into a horrific monster.....

First of all I thought about a new way to make a soccer ball =)
But then frog eggs and pavement stones also came to my mind.

I'm sorry, but my macro does not attempt to model any forces
acting on the blobs. (So my macro can not make them move.)
It only does some calculations on how to modify each the blob
with negative strength components so that close blobs touches
each other at only one point.
(The positions, radii and strength of each blob has to be calculated
by some other code and then passed to my macro in arrays.)
But maybe it would be possible to use my macro with Chris
Huff's particle system patch to make fancy animations of blobs
colliding, being deformed, and then bouncing apart from each
other again.

This is because it really is a Buckminsterfullerene-I-care with
some extra balls in the "middle" of each pentagon and hexagon.
Buckyball:
12 pentagons with a "ball" in each corner: 60 balls
Plus:
12 pentagons with a "ball" in each middle: 12 balls
20 hexagons with a "ball" in each middle: 20 balls
(60 + 12 + 20 "balls")

They look like clumps of cells or organic matter - how would these aunty
blobs works for molecular models?

Maybe I was a little bit unclear about that:
It really is 8 blobs in that image, but each of the 8 blobs
consists of one component with positive strength and
several other components with negative strength.

Hmmm ... interesting idea ... I'll have to muse over this a little bit.
Maybe something like this could be done with a modified version
of my macro ...
... but I'm not quite sure how a cell looks like when it is about to
divide into two cells.
Is it like a "normal" blob with two sphere components ?
Do you (or anyone else in here) know ?
(But I don't think I would have the patience to model the
complete evolution of a monster with POV-script ! ;)
Thank you for commenting.

I thought I would try to give them an organic texture, but I don't

Aunty ?
I'm not sure what kind of molecular models you would like.
Do you have any other images or drawings of such models ?

Do you mean that I'm very close to a dividing cell ?
If so: Is it the image I posted, or is it my suggestion
to use a "normal" two-component blob that is close ?

Don't understand this.
When You travel by car, You can let Your notebook
render all the time, and at each stop, You look at
the pictures and make the next steps.

Hehe ...
But how did you know that I were travelling by car and
that I'm carrying a notebook with me ???
The first days I got so bored when I was sitting on the
ferry (or waiting for it) that I started up POV-Ray and
did some renderings.
But the laptop's LCD is quite bad for viewing the
results, so I became quite frustrated when I couldn't
see clearly the details I wanted to examine in the image.
Therefore I don't render in the car anymore. But I
often think about ideas I have (like these antiblobs)
when I'm travelling.
I have also found that I don't like to render when I'm
feeling alone (like in the car which also is an "off-line
place").
Being online and reading these POV-news groups
inspires me a lot when I'm POV-ing.

Wow that's multi-tasking.
The solution's simple, d/l the newsgroups so that you can read
them off line, and get petrol generator so that you can plug
a standard monitor in and use it with you'r notebook, presumably
you have something that allows you to plug the notebook into
the car's cigarette lighter (to allow you to do renders that take
more than on hour).

I have no idea why, but my first impression upon seeing the first image
was "Rocky Mountain Oysters". Go figure. The second image looks a lot
like some of those molecule models you see in chem labs in school.

Looks great: it resembles a plant virus I used to work with (name: Turnip
Yellow Mosaic Virus). Only this virus particle had something like 60
equivalent blobs: 3 on each of the 20 triangles. Can you do that with
your macro? And: wouldn't this be something nice for POVChem?

The off-line reading of these newsgroups from day to day
only takes about 10-20 minutes. And I do that in the
evenings at internet cafes.
Checking for NEW posts at these newsgroups is much
more exciting than doing nothing while I'm rendering !

I would consider myself very weird if I bought
a petrol generator (or DC/AC voltage converter)
in order to be able to ray trace while driving !

The ferries don't allow any engines to be running ...
And there is something wrong with the laptop battery:
It only lasts for about 15 minutes.

I have been trying to figure out why you get associations
towards oysters ... but I still can't figure ...
But I'm happy that it gave you such strange impressions !

Hmmm ... I try to remember, but it's about 14 years
since I learned about chemistry.
Maybe the models was different back then ?

The macro can take any array of blob centres.
So if you can provide the co-ordinates for the blob
centres, then I can try to write the code for the virus.
Do you have any pictures of this interesting virus ?

Sorry. I don't know POVChem.
Is it a patch ? A collection of macros ?
Or something else ?
Please explain.

Povchem is a shareware program that takes the coordinates of the atoms of
a chemical compound and produces a code that enables Povray to render a
high quality image of that compound. I have used it only a few times to
evaluate it: I have no real use for it. see www.chemicalgraphics.com
(perhaps).
