Hi,

first of all, i'm very new to Pov Ray ;)


Well, I'm trying to render Polyhedra and want the faces to have different
colors.
At the moment I render my polyhedra as intersection of halfspaces, which
works fine.
The question is, how can I give each Face a certain color?

Can someone help?

Thanks in advance,
Philip

  I don't know what a halfspace is, but if you give each one its own
pigment, it should do what you want.

Hi,

since I use the intersection command with planes, i can't give each plane
it's own color(what would solve my problem, i think).I've tried that, and
got back an error :(

thanks anyway

And what did the error say? It should work as Warp suggested

intersection {
  plane {
    ...
    pigment { ... }
  }
  plane {
    ...
    pigment { ... }
  }
  plane {
    ...
    pigment { ... }
  }
  ...
}

Well, it DID work,

I tried to write a comma between the distance and the pigment command.
Sorry for bothering.

Thanks a lot,
Philip

Why not use a difference to obtain the results you want?
Using your sample:
> [snip]

difference {
box {
  ...
     pigment { ... } // doesn't matter what

plane {
  ...
     pigment { ... }
   }
   plane {
     ...
     pigment { ... }
   }
   plane {
     ...
     pigment { ... }
   }
   ...
 }

I didn't try it, it's a thought.

This would work as well and leads to the same result but your version needs
one unnecessary object more (the box) and is therefore slightly slower.
Shouldn't play a role with such a simple object though.

  Why? What would be the advantage?

This is what Philip told us about his problem:

"since I use the intersection command with planes, 
i can't give each plane it's own color(what would 
solve my problem, i think).I've tried that, and
got back an error :("

I was trying to give him an alternative.

I know there is no advantage.
