Hi Slime, 
Thanks for your reply, but I was actually interested in the effect of the
bullet. That is the wave trails it leaves in the air.
The bullet is  travelling and leaving trails. That's what I am looking for.

Thanks once againg.

Fidel.

IIRC, this may be quite difficult.  I think that there were rings of
"turbulence" or whatever coming out as the bullet went through the air -
quite simple if you can get a nice looking transparent texture.
However, I also recall them distorting the background, ie refracting,
but without a solid edge.  This is the only case that I can think of (so
far) where variable IOR would be nice to have.  Perhaps the effect could
be re-created with a set of lens objects, becoming very thin and flat at
the edges (for no distortion), with a sort of ring-like bulge that moves
outwards.  Definitiely a case for isosurfaces or meshes here.

Not finished code ready for the purpose, but maybe something that can
get you started:

#include "transforms.inc"
camera {location <2,3,-8> look_at 0}
light_source {<0,10,0>, color 1}
global_settings {max_trace_level 100}
sky_sphere {pigment {gradient y color_map {[0,rgb 1][1,blue 1]}}}
plane {y, 0 pigment {checker rgb 0.3 rgb 0.9} normal {quilted 0.5}}

#macro BulletWave(Location,Normal,Radius,Strength,Ior)
   intersection {
      cylinder {
         -0.0001*y, 0.0001*y, 1
         pigment {rgbf 1.0}
         normal {cylindrical Strength sine_wave phase -1/4}
      }
      cylinder {
         -0.0002*y, 0*y, 1.2
         pigment {rgbf 1.0}
      }
      interior {ior Ior}
      scale Radius
      transform {Point_At_Trans(Normal)}
      translate Location
   }
#end

#declare StartP = <0,2,-8>;
#declare DirV   = <0.2,0.1,1>/4;
#declare C = 0;
#declare Waves = 100;
#while (C<Waves)
   BulletWave(StartP+C*DirV,DirV,0.3+0.1*sin(C/2),0.02,2)
   #declare C = C+1;
#end

Thank you all for the replies. Rune, that is definitely a start. I'll play
around with it. Thanks a lot.

All the best

Fidel.

Neo has ambient and is illuminating sorrounding bullets and agent :)

Just have a look at this site:

http://www.jefflew.com/articles.html

It's not done in POV-Ray, but perhaps it helps.

Hi Bonsai,

Thanks for the link. I was looking for it again. I had the article on 3D
world mag, but couldn't find it. But anyway, Rune's approach is a good one
as well.

Once again, thank you very much.

All the best

Fidel.

I've got the matrix-movie on DVD and had a look
at it some time ago to actually see what kind
of effect it was.

And the fact is, the bullets are leaving torii. If you
look closely on the last animation where he stops them
in the air, they actually appear very abruptly around
a bullet, something I wouldn't have expected (I remembered
it to be far smoother), and then fade out (which is rather
difficult for us, as the torii would be totally transparent
to begin with, and we could only drop the IOR, which gives
a slightly different effect.

Just my 2 cents worth,

Tim

Hi Tim,

I watched the film again yesterday and I did notice that.

Thanks for the tip. I'll try using torii and see what I get.

Fidel.
