# 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 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 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.
