Tim,

So then you have your first wall so you scale by
<250,260,10>... so
<250,260,10>*<-0.5,-0.5,0>= <-125,-130,0>, and
<250,260,10>*<0.5,0.5,1>=<125,130,10>
which you then translate... so addition
<-125,130,-3.5>+<-125,-130,0> = <-250,0,-3.5>, and
<-125,130,-3.5>+<125,130,10>=<0,260,6.5>
So the first wall is equivalent to
box{<-250,0,-3.5>,<0,260,6.5>}
--------------------------------------------

Where do you come up with the <-0.5,-0.5,0> for multiplication. Why do you
sometimes add then multiply? Where specifically can I learn more about matrix
manipulations in povray? Sorry for being a burden, Thank you.
