gluCylinder — draw a cylinder

## C Specification

```	GLdouble base,
GLdouble top,
GLdouble height,
GLint slices,
GLint stacks )```

## Parameters

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 $z\text{ }=\text{ }\text{height}$. 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.
