gluSphere: draw a sphere.
C Specification |
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).
- Specifies the quadrics object (created with gluNewQuadric).
- Specifies the radius of the sphere.
- Specifies the number of subdivisions around the Z axis (similar to lines
- Specifies the number of subdivisions along the Z axis (similar to lines of
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.
