|
torus, ring general syntax: torus{ rmajor, rminor
texture{ ... ... }
}
In this definition rmajor is the big radius and rminor
is the little radius.
The torus is placed by default in the xz-plane (horizontal) with the y-axis as
the axis of it's rotation symmetry.

|
If another position is needed the torus must be transformed by
"rotate< , , >" and "translate< , , >"
. The radius of the outline is calculated by rtotal = rmajor + rminor . The radius of the hole in the middle of the torus is rinside = rmajor - rminor . | ||

The sample here:
//--------------- the yellow torus in the middle: ------------------
torus {1.0,0.25 scale <1,1,1> rotate<0,0,0> translate<0,0,0>
texture{pigment{color rgb<1,0.65,0>}
finish {ambient 0.15 diffuse 0.85 phong 1}}}
//--------------- the golden torus right in the background: --------
torus {1.0,0.25 scale <1,3,1> rotate<90,0,0> translate<4,3,2>
texture{Polished_Chrome
pigment{color rgb<1,0.8,0>}
normal {bumps 0.5 scale 0.15}
finish {ambient 0.15 diffuse 0.55 phong 1}}}
//---------------the flat silver ring on the left: -----------------
torus {1.0,0.65 scale <1.5,0.33,1> rotate<0,0,90> translate<-1,3,-2>
texture{Polished_Chrome
pigment{color rgb<1,1,0.5>}
normal {bumps 0.5 scale 0.15}
finish {ambient 0.15 diffuse 0.55 phong 1}}}
