PARAMETERS
- quad
-
Specifies the quadrics object (created with gluNewQuadric).
- base
-
Specifies the radius of the cylinder at z = 0.
- top
-
Specifies the radius of the cylinder at z = height.
- height
-
Specifies the height of the cylinder.
- slices
-
Specifies the number of subdivisions around the z axis.
- stacks
-
Specifies the number of subdivisions along the z axis.
DESCRIPTION
gluCylinder draws a cylinder oriented along the z axis. The base of the cylinder
is placed at z = 0, and the top at $ z ~=~ "height" $. Like a sphere,
a cylinder is subdivided around the z axis into slices, and along the
z axis into stacks.
Note that if top is set to 0.0, this routine generates a cone.
If the orientation is set to GLU_OUTSIDE
(with gluQuadricOrientation), then any generated normals
point away from the z axis. Otherwise, they point toward the
z axis.
If texturing is turned on (with gluQuadricTexture), then texture
coordinates are generated so that t ranges linearly from 0.0
at z = 0 to 1.0 at z = height, 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.
