gluSphere
[New
- Windows 95, OEM Service Release 2]
The gluSphere function draws a sphere.

Parameters
qobj
The quadric
object (created with gluNewQuadric).
radius
The radius of
the sphere.
slices
The number of
subdivisions around the z-axis (similar to lines of longitude).
stacks
The number of
subdivisions along the z-axis (similar to lines of latitude).
Remarks
The gluSphere function 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),
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):
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
positive y-axis, to 0.25 at the positive x-axis, to 0.5 at the positive y-axis,
to 0.75 at the positive x-axis, and back to 1.0 at the positive y-axis.
