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...

Kinda looks like Buckminster-who-cares-arene, a buckyball....


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")


> very nice.

Thanks !


> code maybe??

I'll post it to http://news.povray.org/povray.text.scene-files
