NAME

gluCylinder - draw a cylinder

C SPECIFICATION

void gluCylinder(GLUquadric* quad, GLdouble base, GLdouble top, GLdouble height, GLint slices, GLint stacks);

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.
