I just found that POV-Ray had finished this image for me :)

This image also has an "overexposed" area, as Christoph
mentioned about my "Other Bonds" image.

Again I have borrowed code from others:

For the radiosity settings I started with those in 
Xplo's post to povray.text.scene-files in August:

http://news.povray.org/399E20BC.BFD87A13%40unforgettable.com
(Ermm... I modified them without knowing what I was doing.)


And for the textures and colors I modified (slightly)
those that Gilles posted here:

http://news.povray.org/398EE231.F90E52DC%40inapg.inra.fr


The rendering time this for this image was about 6 hours.

Rad! Totally frickin' awesome!!!!
IMO the overexposed area looks cool.
I always liked mushroom shapes. I used to sketch nuclear explosions...

Superb!

I too like the overexposed area.
I assume this is an isosurface?
I sure wish I had your mastery over them.

You might try reducing the light source a bit (to reduce the overexposure)
and set recursion_limit to 2 to weaken the strong shadows in the back
sections.  Also could use an isosurface instead of normal, i posted some
comparison test some time ago:

Of course that would be *really* slow...

Nice! I've admired many of your mathematical images, but the texures
have been less than astonishing :) I'm happy to finally see you
experimenting with textures and radiosity!

Wow. I'm gobsmacked.

I'd like to offer some form of suggestion as to how to improve it ... but I
cant ...

Perfect.

Thanks David !

That's strange. I've been drawing sketches 
of such shapes for about a year now.

But I haven't drawn any nuclear mushrooms yet.

Maybe someone could render such a cloud.
(Perhaps with media =)

Maybe me too can learn to like it overexposed.

No, it's made with CSG.

Now you made me think about how one could
make this shape with an iso.

Unfortunately I don't know how to make
the "blobbing" go inwards and then outwards 
again. Hmmm...

I have now dimmed down the main light source and reduced the 
recursion_limit from 4 to 3 and started a new rendering.

Hopefully I'll see the result tomorrow when I come home from work.

But would this be possible when the shape is made with CSG ?

... Or are there any "iso-normals" in MegaPOV ?

I'm to tired now, so I'll have to look into that tomorrow.


Thanks again for your advice.

Thanks Sigmund.


It has been a long time since I've heard from
another Norwegian in here.

Yes I know. You're very right about my textures :(

I have had a tendency to only use plain pigments 
and some 3 or 4 standard POV-include textures. 

The reason for this might be that when I have 
been thinking of an "geometrical" idea for a day 
or two (or ten ), and then found a solution, done 
all the macro writing and simplifying, I have no 
more patience to tweak textures.

(I only get frustrated when I can't get the 
textures to behave as I want.)

So unfortunately I just skip that texture part, 
and then jump to the part where I can use my 
code to build the shapes I've been "seeing".

The reason for not using those Cool-Tools
within MegaPOV is that I have been afraid that
I should like them so much that I would get 
very angry at my slow PC.
