NAME    [Toc]    [Back]

     gluSphere - draw a	sphere

C SPECIFICATION    [Toc]    [Back]

     void gluSphere( GLUquadric* quad,
		     GLdouble radius,
		     GLint slices,
		     GLint stacks )

PARAMETERS    [Toc]    [Back]

     quad    Specifies the quadrics object (created with gluNewQuadric).

     radius  Specifies the radius of the sphere.

     slices  Specifies the number of subdivisions around the z axis (similar
	     to	lines of longitude).

     stacks  Specifies the number of subdivisions along	the z axis (similar to
	     lines of latitude).

DESCRIPTION    [Toc]    [Back]

     gluSphere draws a sphere of the given radius centered around the origin.
     The sphere	is subdivided around the z axis	into slices and	along the z
     axis into stacks (similar to lines	of longitude and latitude).

     If	the orientation	is set to GLU_OUTSIDE (with gluQuadricOrientation),
     then any normals generated	point away from	the center of the sphere.
     Otherwise,	they point toward the center of	the sphere.

     If	texturing is turned on (with gluQuadricTexture), then texture
     coordinates are generated so that t ranges	from 0.0 at z =	-radius	to 1.0
     at	z = radius (t increases	linearly along longitudinal lines), and	s
     ranges from 0.0 at	the +y axis, to	0.25 at	the +x axis, to	0.5 at the -y
     axis, to 0.75 at the -x axis, and back to 1.0 at the +y axis.
