draw a sphere
C Specification
void gluSphere
GLUquadric* quad
GLdouble radius
GLint slices
GLint stacks
Parameters
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
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.
