I was trying to make arb5 i.e. number 1st object in this link
http://ctrlv.in/363771
I use mesh for this object (but can use mesh2 also) as

#declare Red = texture {
    pigment { color rgb<0.8, 0.2, 0.2> }
    finish { ambient 0.2 diffuse 0.5 }
  }
  #declare Green = texture {
    pigment { color rgb<0.2, 0.8, 0.2> }
    finish { ambient 0.2 diffuse 0.5 }
  }
  #declare Blue = texture {
    pigment { color rgb<0.2, 0.2, 0.8> }
    finish { ambient 0.2 diffuse 0.5 }
  }
#declare Yellow = texture {
    pigment { color rgb<0.5, 0.5, 0.5> }
    finish { ambient 0.2 diffuse 0.5 }
}
mesh
{
triangle{<0, 0, 0> <2, 2, 2> <0, 4, 0>
  texture {Red} }
  triangle{<2, 2, 2> <4, 4, 0> <0, 4, 0>
  texture {Green}}
  triangle{<2, 2, 2> <4, 4, 0> <4, 0, 0>
  texture {Blue}}
  triangle{<2, 2, 2> <0, 0, 0> <4, 0, 0>
  texture {Yellow}}
}

Now I am trying to find out how to make face i.e. 1, 2, 3, 4
in above linked screen-shot.
One way is to make plan but its more complex as I have to first calculate the
normal of that plan. Is there any other way in which I make face using at-least
two vertices?
I want to convert BRL-CAD's arb5 model's vertices into POV-ray's vertices, so I
am looking into easiest way for doing it.
