I gave up the trick with the discs. This is the result. Is this better?

I think it looks good, realism is obviously difficult to judge, since you
can't observe such explosions very often. What's seriously missing is the
interaction with the environment, meaning how the path of the explosion is
influenced by the surrounding objects and also how the objects are damaged
by the explosion. Of course both things are rather difficult to model.
A larger version would be interesting of course.

Hi Rune!
Honestly, I never was able to see any problems with the "discs"... I think
both animations look very good!
You know what would look very cool??? And expanding concentric shockwave. I
really don't know how this could be achieved, but maybe with a growing
sphere with different interior??? And if this shockwave also perturbs the
sand, it would be very realistic. And when the shockwave reaches the
camera.... boom!!! it shakes!!! :D Well, those are just some ideas.
I also think that the smoke dissolves to quickly in the air. I think that
those kind of explosions usually leave a long trail of smoke in the sky.
Fernando.

That's the problem...

Uh, I wouldn't know where to start with that. Could you verbally give an
example of how the path of an explosion could be affected by its
surroundings?

I'll leave that to Chris Colefax's object exploder for now. I might
integrate something into my own particle system at one point, but not in the
first version.

You mean larger resolution? There really aren't a lot of small details...

I really should learn more about shockwaves. I don't know much about what
they are or how they look. I thought they only occurred at explosions much
bigger than the type in this animation?

In any case I'd need reference images and/or animations. :)

That one shouldn't be too hard but would be a great effect. :)

I'll make it possible to control the length of the smoke.

Really? :)
I must admit that I think they look rather similar myself. Besides the
shadow, how's the new one better? And is it worth it?

Depends on the render time :-) I cannot see too much difference between the two;
the both look good (ie. rendering itself is good), but the explosion itself lacks
a certain something. In other words...
technical: 10
realism: 7
Explosions like this (if Hollywood is anything to go by :-) give blacker smoke,
secondary fires, and debris. Computer game explosions in general don't have these
things, which is why your explosion reminds people of them.
If all you were after was a demonstation of your system's capabilities though,
you have achieved it.

How about making that media much more dense... so it loses its transparency
until the smoke has well dissipated?
