Torus

Torus[{x,y,z},{rinner,router}]

represents a torus centered at {x,y,z} with inner radius rinner and outer radius router.

Details and Options

  • Torus is also known as torus of revolution.
  • Torus can be used as a geometric region and a 3D graphics primitive.
  • Torus[] is equivalent to Torus[{0,0,0},{1/2,1}].
  • Torus represents the shell .
  • Torus can be used in Graphics3D.
  • Graphics rendering is affected by directives such as FaceForm, Specularity, Opacity and color.
