Explosion by HE Day (realexplode.pov  in p.b.s-f)
City by Chris Colefax (City.inc)

I tried to add smoke using Mikael Carneholm's SmokeGen v1.2 but it keeps
crashing MegaPOV, it works fine with Official POV but then the explosion
won't work (isosurfaces).

Comments, suggestions.....

I like the explosion. It's kinda cartoony. Great scene.

This is remarkably better. Explosion looks 'real'.

Some quotes from the book:

"Machine it was, with a ringing metallic pace, and long, flexible,
glittering tentacles (one of which gripped a young pine tree) swinging
 and rattling about its strange body.  It picked its road as it went
striding along, and the brazen hood that surmounted it moved to and fro
with the inevitable suggestion of a head looking about.  Behind the main
body was a huge mass of white metal like a gigantic fisherman's basket,
and puffs of green smoke squirted out from the joints of the limbs as
the monster swept by me."

"He [martian tripod] used no Heat-Ray to destroy them, but picked them 
[humans] up one by one.  Apparently he tossed them into the great
metallic carrier which projected behind him, much as a workman's basket
hangs over his shoulder."

The same for me. Can anti-nuclear bunkers protect us from that?

But wonderful picture. As long as I'm not under their Heat-Ray... :))

Try this updated version of realexplode.  It should give less "cartoony"
results.

This is a demonstation of the explosion.  I will add more features

I recommend that you render this with 60 frames or more. Happy destruction!

I liked the original explosion...
Could i see the code...
Please...
I love the rays but am afraid to ask for the code..
Don't want to spoil the magic...

Wonderful image.  Maybe make the flames a tad shorter so we can see the
buildings behind, to give more of a feeling of depth.  I like the
reflections on the buildings in the foreground, but the windows seem a
bit too white.

One thing that caught my eye is that the robot on the right has a
reflection on his underside of the flames/explosions, but the one on the
left does not.

Great image.  Makes me wonder why I would even submit an image when
people are doing this kind of work.  :)

And is it just me, or does Chris Colefax's city generator rock?  Sad
thing is, it might be the best looking part of my submition.  (:

Ooohh. I like. But do the Tripods ever trip over the others legs?

I'll post the complete code when I am finished with the scene, but here is
the Heat Ray

*** Heat Ray Spoiler Alert ***









#declare HeatRayTex =

            }

        }
        finish { ambient 2 }
    }

#declare Ray=union {

Another quote from the book:

"They [martians] did not eat, much less digest. Instead, they took the
fresh, living blood of other creatures, and INJECTED it into their own
veins.  I have myself seen this being done, as I shall mention in its
place.  But, squeamish as I may seem, I cannot bring myself to describe
what I could not endure even to continue watching.  Let it suffice to
say, blood obtained from a still living animal, in most cases from a
human being, was run directly by means of a little pipette into the
recipient canal..."

So yes, you were right.

Perhaps you should post this in povray.binaries.scene-files or 
povray.text.scene-files.

Actually... With the position & orientation of the three legs & the module
on top, I would think that it would tip over as soon as one of the legs
would be lifted.  (I dunno... It just seems 'wrong', but it looks cool! ;-)

Wow, this is just getting better and better. One thing I'd point out is 
that a big explosion like the one you're creating generates a LOT of 
light on its own -- you have some there, but not nearly enough. It also 
generates a lot of dust, but not immediately, so that's probably not as 
important.
