A torus is defined as such:
Note: See the start of 3D Primitives for information about the resolution of three dimensional shapes.
Defaults:
torus() torus({ ri: 1.5, ro: 3 }) torus({ ri: 0.2 }) torus({ fni:4 }) // make inner circle fn = 4 => square torus({ fni:4,roti:45 }) // rotate inner circle, so flat is top/bottom torus({ fni:4,fno:4,roti:45 }) torus({ fni:4,fno:5,roti:45 })
