+.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.
