Hi,

I'm writing a little piece of software, which does some calculations 
about reflections in a room.
The user specifies 6 planes, which are the walls, a 'listener' and a 
'soundsource'.
I want to visualize the room and the first reflections with povray, but 
I've a lot of problems doing so:
The 2 major problems are:
1. I used intersection{ to make the box out of the planes, but since I 
don't know where the planes are, I can't know when I have to do inverse, 
and when not, assuming that every wall will be at another side of 0,0,0 
, but even that isn't for sure. How can I easyly create a box when I 
have only 6 planes?
2. When I've the box created, how can I look "inside", to see what's 
going an? TonyB suggested to make the box out of triangles and take a 
few away, making a hole, but since I have only the 6 planes, I don't 
know how the convert them to triangles and take the right ones away.

I hope someone can help me with this problem,
