Hello everyone, I'm to the newsgroup. I'm having some troubles with the
megapov patch. I downloaded it yesterday, and installed it. I'm trying to
use the isosurfaces so I went to http://www.econym.demon.co.uk/isotut/ to
learn about them. I took this demo from that site:
#version unofficial MegaPov 0.7;

camera { location  <2, 1, -5> look_at <0, 0, 0> angle 60}

sky_sphere { pigment {
    gradient y
    color_map { [0.0 color blue 0.6] [1.0 color rgb 1] }
  }
}

light_source {<-100,200,-100> colour rgb 1}


#declare R = 2;

// ----------------------------------------

isosurface {
  function { x*x + y +z*z - 1 }
        accuracy 0.001
        contained_by{sphere{0,R}}
        pigment {rgb .9}
        finish {phong 0.5 phong_size 10}
}

sphere {0,R pigment {rgbt <1,0,0,0.9>}}

But when I run it I get "returned from renderer (non-zero return value)" I
figured since it was the demo from the site that it should work. Why am I
getting this error and how can I fix it? Any help would be greatly
appreciated.
