fgluSphere(3G)

NAME
     fgluSphere - draw a sphere


FORTRAN SPECIFICATION
     SUBROUTINE fgluSphere( CHARACTER*8 quad,
                            REAL*4 radius,
                            INTEGER*4 slices,
                            INTEGER*4 stacks )


PARAMETERS
     quad    Specifies the quadrics object (created with fgluNewQuadric).

     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
     fgluSphere 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 fgluQuadricOrientation),
     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 fgluQuadricTexture), 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.
