Glu.Cylinder (gb.opengl.glu)
Static Sub Cylinder ( Quad As GluQuadric, Base As Float, Top As Float, Height As Float, Slices As Integer, Stacks As Integer )
draw a cylinder.
Parameters
- quad
-
Specifies the quadrics object (created with Glu.NewQuadric).
- 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
Glu.Cylinder draws a cylinder oriented along the
z axis. The base of the cylinder
is placed at
z = 0 and the top at
.
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 Glu.QuadricOrientation), then any generated normals
point away from the
z axis. Otherwise, they point toward the
z axis.
If texturing is turned on (with Glu.QuadricTexture), 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.
