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, to0.5 at the - Y axis, to 0.75 at the - X axis,
and back to 1.0 at the +Y axis.
