Hi,
Not really math, but this might help:
camera { location <5,1,8> look_at 0 }
light_source { 50 rgb 1 }
plane { y, 0 pigment { rgbt <1,1,1,.5> } }
plane { x, 0 pigment { rgbt <0,1,0,.5> } }
plane { z, 0 pigment { rgbt <0,0,1,.5> } }
difference
{
box { <1,0,1>, <-1,2,-1> }
box { <1,0,1>, <-1,2,-1> translate <.1,-.1,.1> }
translate <1,0,1>
rotate y*-45
translate <0,0,-1>
rotate x*45
pigment { rgb <1,0,0> }
}
Greetings,
Maarten
