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.....

Regards,

Peter H.

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
and functions sometime in the future. Feel free to use this version
in any pic or anim as long as you give me credit for the explosion.

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

I liked the original explosion...
Could i see the code...

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.  (:
