TYPE: SOP
TITLE: Sphere SOP

The Sphere operation generates spherical objects of different geometry types. 
It is capable of creating non-uniform scalable spheres of all geometry types.

Parameters
    Primitive Type   - Type of geometry to create.
    Connectivity     - Type of surface generated when creating a 
		       Mesh or Polygon.
        Rows             - Creates horizontal lines, which are open polygons.
        Column           - Creates vertical lines, which are open polygons.
        Rows & Cols      - Both Rows and Columns.  All polygons are open. 
        Triangles        - Builds the grid with triangles.
        Quads            - Creates four-sided quadrilaterals.
        Alternating Triangles - Creates the grid using alternating triangles.
    
    Radius            - Length of radii along xyz axes.      /radx /rady /radz
    Center            - Position of center of box.           /tx  /ty  /tz

    Orientation       - Poles of sphere align with orientation axis.

    Frequency         - Density of Polygons in a polygonal sphere.    /freq

    Rows              - Number of rows in the sphere                   /rows
    Columns           - Number of columns in the sphere.              /cols

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

    Imperfect         - Approximates the surface using non-rational points.
    Unique Points per Pole - Determines whether points at the poles are shared 
                        or are individual to the columns in meshes, NURBS 
                        and Beziers.
    Accurate Bounds   - If the operation is being used to generate a bounding
                        sphere for its input geometry, this parameter tells
                        us to use a more accurate (but slower) bounding
                        sphere calculation.
