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.
