Hi all,
I created flames with "media" in the new POV-Ray 3.1, but the center of
the flames are
always partial transparent. Flames created with "halo" in POV-Ray 3.02
are not transparent
in the hot flame center and more realistic.
My question: How can i create better flames with "media"?

Many thanks,

Heiko


The problematic code:

#include "colors.inc"
#include "textures.inc"


camera {
  location   < 0, 2, 4 >
 look_at    < 0, 0, 0 >
 }

light_source { < -25, 35, 34 >
color White
}


sphere {
<-.5,0,-1> 1.5
    pigment { color rgbf<1, 1, 1, 1> }
    finish { ambient 0 diffuse 0 }
     interior{
        media{
        emission 0.68
        intervals 5
        samples 5, 10
        confidence 0.999
        variance 1/1000
           density {
                spherical
                ramp_wave
                color_map {
                        [0.0 color rgb <0.0, 0.0, 0.0>]
                        [0.2 color rgb <1.0, 0.0, 0.0>]
                        [1.0 color rgb <1.0, 1.0, 0.0>]
                }

               turbulence 1.9
               frequency 2
               scale .7
           }

        }
     }
    hollow
    scale 1.9

  }


plane

  pigment { checker color White color Black }
}
