TYPE: SOP
TITLE: Torus SOP

The Torus operation generates torus shapes of various types.

Parameters

Torus
    Primitive Type  - Type of geometry to create.
    Surface Type    - Type of surface skinning the torus.
    Orientation     - The plane in which the torus is built.
    Radius          - First value:  The radius of the torus.~r      /radx
		      Second value: The radius of the ring.         /rady
    Center          - Offset of torus center from object origin.    /tx /ty /tz
    Rows            - Number of divisions along the swept shape.    /rows
    Columns         - Number of divisions along the cross-section.  /cols
    Imperfect       - Approximates the surface using non-rational points.

Detail
    U Order         - Order of NURBS/Bezier curve in U direction.   /orderu
    V Order         - Order of NURBS/Bezier curve in V direction.   /orderv

    U Angle         - The start and end sweep angles of the torus.  /beginangleu
								    /endangleu
    V Angle         - The start and end angles of the cross-section
                      circle that is swept to make the torus.       /beginanglev
                                                                    /endanglev
    U Wrap          - Wraps the surface in the U direction.
    V Wrap          - Wraps the surface in the V direction.
    U End Cap       - Puts end-caps on the ends of the torus if it
                      is less than 360 degrees.
    V End Cap       - Applies a face between the top and bottom of 
		      the torus, if it is open.
