-.SH PARAMETERS
-_phead(_param1)
-Specifies the quadrics object (created with _cmnd(NewQuadric)).
-_phead(_param2)
-Specifies the radius of the sphere.
-_phead(_param3)
-Specifies the number of subdivisions around the \f2z\fP axis
-(similar to lines of longitude).
-_phead(_param4)
-Specifies the number of subdivisions along the \f2z\fP axis
-(similar to lines of latitude).
-.SH DESCRIPTION
-_cmnd draws a sphere of the given radius centered around the origin. The
-sphere is subdivided around the \f2z\fP axis into slices and along the
-\f2z\fP axis
-into stacks (similar to lines of longitude and latitude).
-.P
-If the orientation is set to _gluconst(OUTSIDE)
-(with _cmnd(QuadricOrientation)), then any normals generated
-point away from the center of the sphere.
-Otherwise, they point toward the center of the sphere.
-.P
-If texturing is turned on (with _cmnd(QuadricTexture)), then texture
-coordinates are
-generated so that \f2t\fP ranges from 0.0 at $ z ~=~ -^_eqnparam2 $ to 1.0 at
-$ z ~=~ _eqnparam2 $ (\f2t\fP increases linearly along longitudinal
-lines),
-and \f2s\fP ranges from 0.0 at the +\f2y\fP axis, to 0.25 at the
-+\f2x\fP axis,
-to 0.5 at the \-\f2y\fP axis, to 0.75 at the \-\f2x\fP axis, and back to 1.0
-at the +\f2y\fP axis.
